I'm trying to use captcha as it's shown in this example:
http://www.oracle.com/technetwork/developer-tools/jdev/captcha-099103.html
And it works fine in .jspx page or in .jsff page fragment, but I have to place captcha onto the first page of taskflow, and there... it's not updated! /* I mean the button "can't read image" doesn't work */ I have no idea why. Can anybody help?
Actually, I figured out how to do it by myself:
we need captcha image binding in our bean and the resetting method:
private RichImage captchaImage;
public void setCaptchaImage(RichImage captchaImage) {
this.captchaImage = captchaImage;
}
public RichImage getCaptchaImage() {
return captchaImage;
}
public void resetCaptcha(ActionEvent actionEvent) {
captchaImage.setSource("/captchaservlet?rand=" +
String.valueOf(Math.random()));
AdfFacesContext.getCurrentInstance().addPartialTarget(captchaImage.getParent());
}
All, I didn't know how to do was adding parameter to "/captchaservlet"
And now it works fine :)
But the next problem appears: when returning to this page with captcha from the second one in task flow I need to refresh captcha image. Is there any method that is executed on page return or something?
Aaaaaaaaaaaand I found even more elegant solution: one should just set the source of the captcha image to this method using the expression builder:
public String getCaptchaSource() {
return "/captchaservlet?rand=" + String.valueOf(Math.random());
}
The button "Refresh", of course, should be set as a partial trigger for the image, as in the example.
And that's it :)

I have been writing selenium scripts for a while in Java. I encountered a very weird issue today. Here is the issue:
I cleared a text field using webelement.clear() method, later while executing next command (click event), the text area I had previously cleared, is now populated with previously filled value.
Here is the code snippet:
mobileNumField.get(0).clear();
Thread.sleep(4500);
emailAddress.get(0).click();
emailAddress.get(0).clear();
Thread.sleep(4500);
emailAddress.get(0).sendKeys(Keys.TAB);
I don't know the exact reason for your element keeping its value, but you can try an alternative text clearance by sending 'Ctrl+A+Delete' key combination using sendKeys method of the element's object:
emailAddress.sendKeys(Keys.chord(Keys.CONTROL,"a", Keys.DELETE));
It's possible that the fields you're trying to fill has autocomplete attribute set to on. [Reference]
If clear() works when the line executes then it's safe to say that this is not a webdriver specific issue.
It would help if you can show the html snippet of the page section you're working on.
Possible areas of debugging:
forcefully remove autocomplete attribute on page load using java script executor
turn off autocomplete setting on the driver level. I believe the solution would vary depending on the driver being used.
Good luck!
PS: Those Thread.sleep(s) are not advisable.
I solved it by adding a function to my BasePage to clear fields by a given WebElement.
public void clearWebField(WebElement element){
while(!element.getAttribute("value").equals("")){
element.sendKeys(Keys.BACK_SPACE);
}
}
You can also implement this method in the page that experiencing the problem.
I am using Mac and the following code helps also
public static void macCleanHack(WebElement element) {
String inputText = element.getAttribute("value");
if( inputText != null ) {
for(int i=0; i<inputText.length();i++) {
element.sendKeys(Keys.BACK_SPACE);
}
}
}
I had a similar issue with a text field that used an auto-complete plugin. I had to explicitly clear the attribute value as well as do a SendKeys. I created an extension method to encapsulate the behaviour, hopefully the snippet below will help:
public static void SendKeysAutocomplete(this IWebElement element, string fieldValue)
{
element.SendKeys(fieldValue);
element.SetAttribute("value", fieldValue);
}
public static void SetAttribute(this IWebElement element, string attributeName, string attributeValue)
{
var driver = WebDriverHelper.GetDriverFromScenarioContext();
var executor = (IJavaScriptExecutor)driver;
executor.ExecuteScript("arguments[0].setAttribute(arguments[1], arguments[2]);", element, attributeName, attributeValue);
}
Faced a similar problem. The input field is cleared but the error message is not updated. It seems that some input fields work correctly only if you enter and delete a character:
element.sendKeys(text);
element.sendKeys(Keys.SPACE, Keys.BACK_SPACE);
Hope this helps to clear the field and then sendKeys() the needed value
while (!inputField.getAttribute("value").equals("")) {
inputField.sendKeys(Keys.BACK_SPACE);
}
inputField.sendKeys("your_value");
In some webforms clearing the field followed by .sendKeys() won't work because it keeps repopulating it with some autofill value (in my case it was due to an onfocus attribute function of an input element). Action chains didn't help, the only thing that worked for me was replacing the value attribute directly with javascript:
In Java:
driver.executeScript("document.getElementById('elementID').value='new value'");
In Python (nearly identical):
driver.execute_script("document.getElementById('elementID').value='new value'")
For more on the Java version of this solution see this question.
I want to create a maintenance Page for my cake website by checking a Database Table for a maintenance flag using a sub-function of my AppController "initilize()" method. If the flag is set, i throw my custom MaintenanceException(Currently containing nothing special):
class MaintenanceException extends Exception{
}
To handle it, I implemented a custom App Exception Renderer:
class AppExceptionRenderer extends ExceptionRenderer {
public function maintenance($error)
{
return "MAINTENANCE";
}
}
I am able to see this maintenance Text on my website if I set my DB flag to true, but I could not find any information in cake's error handling documentation (http://book.cakephp.org/3.0/en/development/errors.html) on how I can actually tell the Exception renderer to render view "maintenance" with Template "infopage".
Can I even us that function using the ExceptionRenderer without a custom error controller? And If not, how should a proper ErrorController implementation look like? I already tried this:
class AppExceptionRenderer extends ExceptionRenderer {
protected function _getController(){
return new ErrorController();
}
public function maintenance($error)
{
return $this->_getController()->maintenanceAction();
}
}
together with:
class ErrorController extends Controller {
public function __construct($request = null, $response = null) {
parent::__construct($request, $response);
if (count(Router::extensions()) &&
!isset($this->RequestHandler)
) {
$this->loadComponent('RequestHandler');
}
$eventManager = $this->eventManager();
if (isset($this->Auth)) {
$eventManager->detach($this->Auth);
}
if (isset($this->Security)) {
$eventManager->detach($this->Security);
}
$this->viewPath = 'Error';
}
public function maintenanceAction(){
return $this->render('maintenance','infopage');
}
}
But this only throws NullPointerExceptions and a fatal error. I am really dissapointed by the cake manual as well, because the code examples there are nowhere close to give me an impression of how anything could be done and what functionality I actually have.
Because I had some more time today, I spent an hour digging into the cake Source and found a solution that works well for me (and is propably the way it should be done, altough the cake documentation does not really give a hint):
Step 1: Override the _template(...)-Method of the ExceptionRenderer in your own class. In my case, I copied the Method of the parent and added the following Code at the beginning of the method:
$isMaintenanceException = $exception instanceof MaintenanceException;
if($isMaintenanceException){
$template = 'maintenance';
return $this->template = $template;
}
This tells our Renderer, that the error Template called "maintentance"(which should be located in Folder: /Error) is the Error Page content it should render.
Step 2: The only thing we have to do now (And its is kinda hacky in my opinion, but proposed by the cake documentation in this exact way) is to set the layout param in our template to the name of the base layout we want to render with. So just add the following code on top of your error template:
$this->layout = "infopage";
The error controller I created is actually not even needed with this approach, and I still don't know how the cake error controller actually works. maybe I will dig into this if I have more time, but for the moment.
Error like:The view 'LoginRegister' or its master was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/MyAccount/LoginRegister.aspx
~/Views/MyAccount/LoginRegister.ascx
~/Views/Shared/LoginRegister.aspx
~/Views/Shared/LoginRegister.ascx
~/Views/MyAccount/LoginRegister.cshtml
~/Views/MyAccount/LoginRegister.vbhtml
~/Views/Shared/LoginRegister.cshtml
~/Views/Shared/LoginRegister.vbhtml
Actually my page view page is ~/Views/home/LoginRegister.cshtml so what i do
and my RouteConfig is
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "MyAccount", action = "LoginRegister", id = UrlParameter.Optional }
);
}
}
Be careful if your model type is String because the second parameter of View(string, string) is masterName, not model. You may need to call the overload with object(model) as the second parameter:
Not correct :
protected ActionResult ShowMessageResult(string msg)
{
return View("Message",msg);
}
Correct :
protected ActionResult ShowMessageResult(string msg)
{
return View("Message",(object)msg);
}
OR (provided by bradlis7):
protected ActionResult ShowMessageResult(string msg)
{
return View("Message",model:msg);
}
Problem:
Your View cannot be found in default locations.
Explanation:
Views should be in the same folder named as the Controller or in the Shared folder.
Solution:
Either move your View to the MyAccount folder or create a HomeController.
Alternatives:
If you don't want to move your View or create a new Controller you can check at this link.
In Microsoft ASP.net MVC, the routing engine, which is used to parse incoming and outgoing URL Combinations, is designed with the idea of Convention over Configuration. What this means is that if you follow the Convention (rules) that the routing engine uses, you don't have to change the Configuration.
The routing engine for ASP.net MVC does not serve web pages (.cshtml). It provides a way for a URL to be handled by a Class in your code, which can render text/html to the output stream, or parse and serve the .cshtml files in a consistent manner using Convention.
The Convention which is used for routing is to match a Controller to a Class with a name similar to ControllerNameController i.e. controller="MyAccount" means find class named MyAccountController. Next comes the action, which is mapped to a function within the Controller Class, which usually returns an ActionResult. i.e. action="LoginRegister" will look for a function public ActionResult LoginRegister(){} in the controller's class. This function may return a View() which would be by Convention named LoginRegister.cshtml and would be stored in the /Views/MyAccount/ folder.
To summarize, you would have the following code:
/Controllers/MyAccountController.cs:
public class MyAccountController : Controller
{
public ActionResult LoginRegister()
{
return View();
}
}
/Views/MyAccount/LoginRegister.cshtml: Your view file.
In your LoginRegister action when returning the view, do below, i know this can be done in mvc 5, im not sure if in mvc 4 also.
public ActionResult Index()
{
return View("~/Views/home/LoginRegister.cshtml");
}
Check the build action of your view (.cshtml file) It should be set to content. In some cases, I have seen that the build action was set to None (by mistake) and this particular view was not deploy on the target machine even though you see that view present in visual studio project file under valid folder
This could be a permissions issue.
I had the same issue recently. As a test, I created a simple hello.html page. When I tried loading it, I got an error message regarding permissions. Once I fixed the permissions issue in the root web folder, both the html page and the MVC rendering issues were resolved.
Check whether the View (.ASPX File) that you have created is having the same name as mentioned in the Controller. For e.g:
public ActionResult GetView()
{
return View("MyView");
}
In this case, the aspx file should be having the name MyView.aspx instead of GetView.aspx
I got this error because I renamed my View (and POST action).
Finally I found that I forgot to rename BOTH GET and POST actions to new name.
Solution : Rename both GET and POST actions to match the View name.
If the problem happens intermittently in production, it could be due to an action method getting interrupted. For example, during a POST operation involving a large file upload, the user closes the browser window before the upload completes. In this case, the action method may throw a null reference exception resulting from a null model or view object. A solution would be to wrap the method body in a try/catch and return null. Like this:
[HttpPost]
public ActionResult Post(...)
{
try
{
...
}
catch (NullReferenceException ex) // could happen if POST is interrupted
{
// perhaps log a warning here
return null;
}
return View(model);
}
I had this same issue.
I had copied a view "Movie" and renamed it "Customer" accordingly.
I also did the same with the models and the controllers.
The resolution was this...I rename the Customer View to Customer1 and
just created a new view and called it Customer....I then just copied
the Customer1 code into Customer.
This worked.
I would love to know the real cause of the problem.
UPDATE
Just for grins....I went back and replicated all the renaming scenario again...and did not get any errors.
I came across this error due to the improper closing of the statement,
#using (Html.BeginForm("DeleteSelected", "Employee", FormMethod.Post))
{
} //This curly bracket needed to be closed at the end.
In Index.cshtml view file.I didn't close the statement at the end of the program. instead, I ended up closing improperly and ran into this error.
I was sure there isn't a need of checking Controller ActionMethod code because I have returned the Controller method properly to the View. So It has to be the view that's not responding and met with similar Error.
If you've checked all the things from the above answers (which are common mistakes) and you're sure that your view is at the location in the exceptions, then you may need to restart Visual Studio.
:(
In my case, I needed to use RedirectToAction to solve the problem.
[HttpGet]
[ControleDeAcessoAuthorize("Report/ExportToPDF")]
public ActionResult ExportToPDF(int id, string month, string output)
{
try
{
// Validate
if (output != "PDF")
{
throw new Exception("Invalid output.");
}
else
{
...// code to generate report in PDF format
}
}
catch (Exception ex)
{
return RedirectToAction("Error");
}
}
[ControleDeAcessoAuthorize("Report/Error")]
public ActionResult Error()
{
return View();
}
I ran into this a while ago and it drove me crazy because it turned out to be simple. So within my View I was using a grid control that obtained data for the grid via an http request. Once the middle tier completed my request and returned the dataset, I received the same error. Turns out my return statement was 'return View(dataset);' instead of 'return Json(dataset);
I couldn't find any solution to this problem, until I found out the files didn't exist!
This took me a long time to figure out, because the Solution Explorer shows the files!
But when I click on Index.cshtml I get this error:
So that was the reason for this error to show. I hope this answer helps somebody.
I'm writing an Eclipse plugin, I want to create a wizard for my new project type. I created pages by classes extends org.eclipse.jface.wizard.WizardPage. My requirement is, based on some condition in one page, I need to go back to previous page without pressing back button on page(programmatically).
Is it possible?
Thanks a million in advance!
I don't think this is a good idea. The user will be confused by doing this. I would disable the finish and the next button and give an error, telling the user that he has to go back to the first page.
If you want to reuse some UI from the first page, define the UI as a new class and reuse it.
I implemented something similar using the WizardDialog:showPage() method:
MyWizard.java
public void createPageControls(Composite pageContainer) {
// TODO Auto-generated method stub
super.createPageControls(pageContainer);
wizardDialog = (WizardDialog) getContainer();
}
public void skipProcessPage() {
wizardDialog.showPage(workPage == arisDbPage ? focusPage : arisDbPage);
}
public void setWorkPage(IWizardPage workPage) {
this.workPage = workPage;
}
here the processPage does the lengthy db lookup!

So let me put it this way.
I have a LogInViewModel and a LogInView. There is a Login() method in the ViewModel that gets called if the user clicks on a button in the View. Now I want the dashboard to show if the login was successful. How do I do this? I can't find a clear answer to this in the documentation.
I assume that your dashboard is essentially your shell. In which case, you can bootstrap your LoginViewModel and in the Login method, after a successful login, you can show the DashboardViewModel and close the LoginViewModel using the Caliburn.Micro WindowManager.
Something like (using MEF):
Bootstrapper.cs
public class Bootstrapper : Caliburn.Micro.Bootstrapper<ILoginViewModel>
{
...
}
LoginViewModel.cs
public class LoginViewModel : Screen, ILoginViewModel
{
private readonly IWindowManager windowManager;
private readonly IDashboardViewModel dashboardViewModel;
[ImportingConstructor]
public LoginViewModel(IWindowManager windowManager, IDashboardViewModel dashboardViewModel)
{
this.windowManager = windowManager;
this.dashboardViewModel = dashboardViewModel;
}
public void Login()
{
// if login success...
this.windowManager.ShowDialog(this.dashboardViewModel);
this.TryClose();
}
}
I've just added a very simple login example SL4 project in my "lab repository" for Caliburn.Micro.
https://github.com/jenspettersson/Caliburn.Micro.Labs/tree/master/src/Login
It uses the Show class that Rob Eisenberg uses in his "Game Library" example to switch between views.
In the Login() method, it tells my Shell (your dashboard?) to show my LoginResultViewModel and sets the login result message.
yield return Show.Child<LoginResultViewModel>().In<IShell>().Configured(c => c.ResultMessage = "Successfully logged in!");
Check the code in my github repo.
I havent used Caliburn.Micro very much lately, so I am by no means an expert, but this way works for me.
//J
Edit: This answers how to navigate between views, if you want to show a "popup" to display if the login was successful, go with the other recomendations.
