I have custom validation added to my page, and this validation is called from business logic layer, after I click "Save" button on UI, which is AjaxSubmitLink.
On my page I have apache wicket DateTimeField, but it's validation doesn't work correctly: error message doesn't appear in FeedbackPanel, which is added on page and my custom validation is shown there correctly.
So for example I fill hours field with "321" and I will have error in console:
WARN org.apache.wicket.protocol.http.WebSession -
Component-targetted feedback message was left unrendered. This could
be because you are missing a FeedbackPanel on the page. Message:
[FeedbackMessage message = "Translation for key [hours.RangeValidator]
is not found for language [en]!", reporter = hours, level = ERROR]
Maybe someone had similar problems and have solution for this?
Thanks!
Because you do an Ajax-Request you have to add the feedback-panel to your AjaxRequestTarget (so it will update itself on every request).
You have to override the onError method though:
add(new AjaxSubmitLink() {
#Override
protected void onError(final AjaxRequestTarget target, final Form form) {
target.addComponent(yourFeedbackPanel);
}
}

I am new to ZK framework. As per my requirement, I need to convert JSP-Servlet based application into ZK framework. One requirement is I need to show previously filled data [stored in browser cache] in forms input boxes when user click in that input box or type similar characters.
This was the default behavior in the JSP-Servlet application or any other HTML based GUI. But by default ZK form does not show previously filled data. I tried some googling to find its solution but could not found any. Please provide me the solution for that.
Thanks in advance :)
You can use cookies for that.
Here is a link to the documentation of cookies for zk.
Code provided in the link :
public void onCookie(){
try {
//add cookie
HttpServletResponse response = (HttpServletResponse)Executions.getCurrent().getNativeResponse();
Cookie userCookie = new Cookie("user", "xxx123");
response.addCookie(userCookie);
//get cookie
Cookie [] cookies = ((HttpServletRequest)Executions.getCurrent().getNativeRequest()).getCookies();
System.out.println(cookies[0].getName());
} catch (Exception e) {
e.printStackTrace();
}

If you are in Magento 1.9.1 Here is a solution which worked for me.
If your theme doesn’t include any specific custom config or layout settings you can safely delete your customer.xml (or just rename to customer1.xml) file located at /app/design/frontend/default/<your_theme_package>/<your_theme_name>/layout/customer.xml
If you delete this file magento will load the default config options
(with the updates) from the factory default magento theme.
/app/design/frontend/base/default/layout/customer.xml
Remember to flush / refresh your magento config via administration area, this will force the customer.xml file to be reloaded.
It seems that your invoking an udeclared object, so maybe it's only a variable.
Verify if you're declaring your object before the line 750 in your AccountController.php
You must put the declaration of the object (Example: $ob = new Customer();)
that contains the setCustomerId() method, into the method that is running.
login to magento. go to system, design. Delete your current theme and then re-add again.
In a Hub view App with subItems Pages, my question is when I navigate to a sub item detail Page and then use command navigate goback, the view always returns to pageroot hub section01.
How can I return the MainHub Page to the original calling section that went to the sub page in the first place?
My research has been fruitless. I don't think snaps are my answer but hey any advice is appreciated.
I apologize if this is a very simple question but...
Thx.
Ok. Thanks for the answers. After looking at this problem for three days I have found a solution but not quite an answer.
this.NavigationCacheMode = Windows.UI.Xaml.Navigation.NavigationCacheMode.Enabled;
By enabling Navigation Caching the page will return to it's sender position. However I still desire to return to the Hub root page to a specific section. If anyone still has info on how to achieve this I would be grateful.
Seasons Greetings.
Well the newbie here has also discovered the MyHub.ScrollToSection(MyHub.Sections[0]);
This allows you to navigate directly to a section thereby bringing it into the current view.
I'm trying to find an answer to the same question. This is what I've found so far. I welcome any better solutions.
Option 1
Enable caching for the page. Note that this must be set in the page constructor or XAML. This will increase memory usage but will improve performance of your app when you navigate back to a cached page.
this.NavigationCacheMode = Windows.UI.Xaml.Navigation.NavigationCacheMode.Enabled;
More information here: http://msdn.microsoft.com/en-us/library/windows/apps/xaml/windows.ui.xaml.controls.page.navigationcachemode.aspx
Option 2
Manually save a controls state between page navigations. The example below is using the NavigationHelper class which is added to a new Windows Store project by default.
private void OnNavigationHelperSaveState(obj sender, SaveStateEventArgs e)
{
e.PageState["SelectedSection"] = this.MainHub.SectionsInView;
}
private void OnNavigationHelperLoadState(obj sender, LoadStateEventArgs e)
{
if (e.PageState != null)
{
var sections = e.PageState["SelectedSection"] as IList<HubSection>;
if (sections != null && sections.Any())
{
this.MainHub.ScrollToSection(sections[0]);
}
}
}
More information here: http://msdn.microsoft.com/en-gb/library/windows/apps/hh986968.aspx
you could get the Hub's descendant scrollviewer and register to scrollchanged events, store the scrollOffsets and restore them as soon as the user navigates back to the page by applying the values to the hub's scrollviewer.
I guess you would have to register to the hub's loaded event to get the descending scrollviewer (you can use an Extension method from WinRt XAML Toolkit that allows you to get the descendants by Type (e.g. Scrollviewer)
greetings!
you can delete un back stack with this :
if(this.Frame.CanGoBack)
{
this.Frame.BackStack.RemoveAt(0);
}
Have you tried what i suggested?
Unforunately Hub can't be extended to do this and access it's Scrollviewer so you have to do this with an attached Property or plainly in your page.cs .
First you register an handler for the Loaded event of your hub. In the handler you get the descending scrollviewer (with the help of WINRT XAML Toolkit maybe) and register for it's ViewChanged Event.
You store the paremeters you like somewhere they don't get deleted on page navigation and restore and attach them to the scrollviewer on backwards-navigation.
I can give you example code in the afternoon.
Greetings
It's not a ridiculous request. Try this:
public static class Concurrency
{
public static HubSection GotoSection { get; set; }
}
public class MainPage : Page
{
protected override void OnNavigatedTo(NavigationEventArgs e)
{
if (Concurrency.GotoSection != null)
MainHub.ScrollToSection(Concurrency.GotoSection);
Concurrency.GotoSection = null;
base.OnNavigatedTo(e);
}
protected override void OnNavigatedFrom(NavigationEventArgs e)
{
Concurrency.GotoSection = MainHub.SectionsInView.First();
base.OnNavigatedFrom(e);
}
}
The reason this.NavigationCacheMode = Windows.UI.Xaml.Navigation.NavigationCacheMode.Enabled; may not be the correct solution is because you might want your hub to be refreshed. If the detail page resulted in an edit (or especially a delete) a back navigation would show stale data, and subject your app to un unexpected state if the user interacts with dead data.
Best of luck!
Enable cache mode on your page at initialization
public MainHubPage()
{
. .......
this.NavigationCacheMode = NavigationCacheMode.Enabled;
.......
}
You need to add Loaded method to Page constructor.
MainHub.Loaded += async (s, e) => await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
//here you can scroll
MainHub.ScrollToSection(Loyaltysection);
});
I have to port some legacy code, that uses modal dialog boxes all over the place to Metro/WinRT (using C++/CX). Because these dialog boxes provide their own message loop (using DialogBoxParam()), the calling code will wait until the user has clicked a button on the message box.
I'm currently trying to write a replacement for the old message box class, that uses XAML and the popup control. To reproduce the same behavior, I have to wait in the calling thread, but also have to keep the UI responsive. I've found out, that CoreDispatcher::ProcessEvents() can be used in a loop, to keep processing events (yeah I realize that this isn't very beautiful, but I don't want to change all of our legacy code to a new threading model). However I'm running into an issue that keeps crashing my app.
Here is a minimal example that reproduces the issue (just create a XAML app and wire this to a button):
void CPPXamlTest::MainPage::Button_Click_1(Platform::Object^ sender, Windows::UI::Xaml::RoutedEventArgs^ e)
{
bool cancel = false;
auto popup = ref new Popup();
auto button = ref new Button();
button->Content = "Boom";
auto token = (button->Click += ref new RoutedEventHandler([&cancel] (Object ^, RoutedEventArgs ^) { cancel = true; }));
popup->Child = button;
popup->IsOpen = true;
while (!cancel)
{
Window::Current->Dispatcher->ProcessEvents(CoreProcessEventsOption::ProcessOneAndAllPending);
}
popup->IsOpen = false;
button->Click -= token;
}
This seems to work well for the first one or two tries of opening and closing the popup, using the two buttons. After a few tries however, the application will instantly crash deep in Windows.UI.Xaml.dll, while trying to dereference a null pointer. I can also reproduce this in C# (with practically the same code).
Does anyone have an idea, what is going on in here? Or a suggestion for an alternative approach?
If anyone is interested: I asked the same question a few days later on the MSDN forums and got a response there from a Microsoft employee:
http://social.msdn.microsoft.com/Forums/en-US/winappswithnativecode/thread/11fa65e7-90b7-41f5-9884-80064ec6e2d8/
Apparently the problem here is the nested message loop that is caused by calling ProcessEvents inside an event handler. It seems that this is not supported by WinRT, but instead of failing in a well-defined manner, this will or may cause a crash.
Alas this was the best and only answer I could find, so I ended up working around the problem, by dispatching the event handler (and a lot of other code) into another thread. I could then emulate the waiting behavior of DialogBox()/DialogBoxParam() (outside the main thread), by waiting on an event that was signaled when the user clicked/tapped a button on my XAML "dialog" popup.
A workaround that works fine for me is to replace the line:
Window::Current->Dispatcher->ProcessEvents(CoreProcessEventsOption::ProcessOneAndAllPending);
with:
auto myDispatchedHandler = ref new DispatchedHandler([&](){
Window::Current->Dispatcher->ProcessEvents(CoreProcessEventsOption::ProcessOneAndAllPending);
});
dispatcher->RunAsync(CoreDispatcherPriority::Normal,myDispatchedHandler);

I am creating a silver light application using Navigation app template. It is for internal use and hence uses windows authenticatoin. There is a dashboard page which shows couple of records filtered by logged in users id. To get the user id (which is an int) I call a web service by overriding the GetAuthenticatedUser and pass the username (from IPrincipal). This service takes some time to return the details.
When I navigate to dashboard app, it renders completely with no data because the user service is a async operation and I am not able to make the rendering wait till my GetAuthenticatedUser finishes completely. So I created a Login page which just shows a progress bar till I get the user object and then navigate to dashboard. If someone tries to access the dashboard directly by using the URL, i want them to navigate back to Login page.
So in the dashboard constructor I added the following code
if (!UserService.Current.User.IsAuthenticated)
{
MessageBox.Show("Navigating away");
Frame objContainer = this.Parent as Frame;
objContainer.Navigate(new Uri("/Views/Login.xaml", UriKind.Relative));
}
Thogh I get the message box prompt, it does not actually take me to Login page but stays in dashboard page. I also tried putting this code in OnNavigatedTo override with no luck.
I also tried using NavigationService instead of Frame as below, with no luck
if (!UserService.Current.User.IsAuthenticated)
{
MessageBox.Show("Navigating away");
this.NavigationService.Navigate(new Uri("/Views/Login.xaml", UriKind.Relative));
}
it still does not work. Does anyone know how to make some page accessible only if I have fully valid user object? if they try to access the restricted page without this, I want them to be able to redirected to Login page, how can this be achieved?
I am using Silverlight 3 Beta

I finally found a way around this. In the Constructo i Hooked up the Loaded event handler and in the event handler I am navigating to a different page and it works fine now.
public Dashboard()
{
InitializeComponent();
this.Loaded += new RoutedEventHandler(Dashboard_Loaded);
}
void Dashboard_Loaded(object sender, RoutedEventArgs e)
{
if (!UserService.Current.User.IsAuthenticated)
{
Frame objContainer = this.Parent as Frame;
if (objContainer != null)
{
objContainer.Navigate(new Uri("/Views/Login.xaml", UriKind.Relative));
}
}
}
This piece of code works just fine!
