i add a new window in windowapplication,i did by nativeWindow,but when i debug this,the new window's content is always not loading completely.
the following is the error
TypeError: Error #1009: Cannot access a property or method of a null object reference.
i did add the creation_complete event,but it still not work.
why?someone could help?
opts = new NativeWindowInitOptions();
opts.resizable=false;
opts.maximizable=false;
win = new NativeWindow(opts);
win.alwaysInFront=true;
var newWindow:TestWindow=new TestWindow();
newWindow.addEventListener(FlexEvent.CREATION_COMPLETE,performWindowComplete);
win.activate();
public function performWindowComplete(e:FlexEvent):void
{
win.stage.addChild(e.currentTarget as TestWindow);
}
and in the TestWindow ,I just add one textArea,when i open this new window,i click the textarea,it throws null object.i confused.
CREATION_COMPLETE event never fire because your component not added in display list/stage.First you need to add to display list.
opts = new NativeWindowInitOptions();
opts.resizable=false;
opts.maximizable=false;
win = new NativeWindow(opts);
win.alwaysInFront=true;
var newWindow:TestWindow=new TestWindow();
newWindow.addEventListener(FlexEvent.CREATION_COMPLETE,performWindowComplete);
win.addElement(newWindow); //Todo
win.activate(); //or Set visible = true

In my Windows 8 App, I have a Popup which displays when clicking a link on the charm bar. How do I pass the current applications visible frame to the the popup? I would like to display and do different things based on where they call the charms bar and open the settings.
To create my settings popup i do the following:
void onCommandsRequested(SettingsPane settingsPane, SettingsPaneCommandsRequestedEventArgs eventArgs)
{
UICommandInvokedHandler handler = new UICommandInvokedHandler(onSettingsCommand);
SettingsCommand generalCommand = new SettingsCommand("SettingId", "Setting", handler);
eventArgs.Request.ApplicationCommands.Add(generalCommand);
}
void onSettingsCommand(IUICommand command)
{
// Create a SettingsFlyout the same dimenssions as the Popup.
MyApp.Common.LayoutAwarePage mypane = new SettingsFlyout;
}
I think you can pass current frame as DataContext to popup.
var popup = new Popup();
popup.DataContext = this;
I'm trying to update a windows 8 application from the Developer Preview to the Consumer Preview. It seems there's been a few changes. This code used to work:
var myDataSource = new WinJS.UI.ArrayDataSource(array)
var basicListView = WinJS.UI.getControl(document.getElementById("basicListView"));
basicListView.dataSource = myDataSource;
Now, there is no WinJS.UI.getControl method and no ArrayDataSource. This is my code:
var dataList = new WinJS.Binding.List(array);
var list = document.getElementById("basicListView");
list.itemDataSource = dataList.dataSource;
but it does nothing (except add a property to a DOM element that is ignored). Any ideas what I'm missing?
Got it. To get the control you now use the winControl property of the element:
var list = document.getElementById("basicListView").winControl;
Setting the itemDataSource works a treat.
I have an Infopath 2010 template with 2 buttons: submit and cancel. When the submit button is clicked I the form is saved to a document library in SharePoint 2010 and the corresponding workflow is clicked off. The user can then open the form and cancel the request by clicking on cancel. I would like to start a different workflow when cancel is clicked. Any ideas as to how that could be done?
Thanks
I have not found a method to kick off a workflow specifically from an Infopath form. I did however find a workaround; here's how I set it up:
Added a column to my list/library that will be set to true when the cancel button is selected.
In my infopath form, add my "cancel" button.
Open the control properties for the button, and select the "Rules" action. Close out of the properties dialog.
I added a fomatting rule for the cancel button so it will only display if the first workflow has started. I also disabled all other editing controls as I only wanted the cancel option to be available.
On the Control Tools contextual tab, in the Button group, click Manage Rules.
Add a new Action rule, it should run two actions: first set the value of the column we created in the first step to true; second submit data using the main data connection.
The workflow you want to run when it is cancelled should be set to run on change. As a first step, evaluate the column created above, and if true, continue the worflow. Make sure you set the value back to false so the workflow doesn't run unintentionally.
Hope that helps.
That is not a bad workaround Nostromo but we actually ended up using the out of the box SharePoint web services to start the workflow from InfoPath code behind. Here is the method we developed to do that.
public static void StartWorkflow(string siteUrl, string docUrl,string workflowName, List<string> approvers,string description)
{
var workflow = new Workflow();
workflow.Url = siteUrl+ "/_vti_bin/workflow.asmx";
workflow.Credentials = System.Net.CredentialCache.DefaultCredentials;
XmlNode assocNode = workflow.GetTemplatesForItem(docUrl);
XmlNamespaceManager nsmgr = new XmlNamespaceManager(assocNode.OwnerDocument.NameTable);
nsmgr.AddNamespace("wf", "http://schemas.microsoft.com/sharepoint/soap/workflow/");
XmlDocument doc = new XmlDocument();
Guid templateID = new Guid();
bool workflowFound = false;
XPathNodeIterator rows = assocNode.CreateNavigator().Select("//wf:WorkflowTemplate", nsmgr);
while (rows.MoveNext())
{
if (rows.Current.GetAttribute("Name", "").ToLower() == workflowName.ToLower())
{
doc.LoadXml(rows.Current.SelectSingleNode("wf:AssociationData/wf:string", nsmgr).Value);
XPathNavigator idNode = rows.Current.SelectSingleNode("wf:WorkflowTemplateIdSet", nsmgr);
templateID = new Guid(idNode.GetAttribute("TemplateId", ""));
workflowFound = true;
break;
}
}
if(!workflowFound)
throw new Exception("System couldn't location the workflow with name: " +workflowName);
XmlElement xmlRoot = doc.DocumentElement;
nsmgr = new XmlNamespaceManager(assocNode.OwnerDocument.NameTable);
nsmgr.AddNamespace("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD");
xmlRoot.SelectSingleNode("/my:myFields/my:Description", nsmgr).InnerText = description;
XmlNode reviewersNode = xmlRoot.SelectSingleNode("/my:myFields/my:Reviewers", nsmgr);
reviewersNode.InnerXml = "";
foreach (var user in approvers)
{
XmlNode personNode = reviewersNode.AppendChild(doc.CreateElement("my:Person"));
XmlNode accountIdNode = personNode.AppendChild(doc.CreateElement("my:AccountId"));
accountIdNode.InnerText = user;
XmlNode accountTypeNode = accountIdNode.AppendChild(doc.CreateElement("my:AccountType"));
accountTypeNode.InnerText = "User";
}
XmlNode workflowNode = workflow.StartWorkflow(docUrl, templateID, doc.DocumentElement);
}
I'm a complete newbie at Dojo, and Adobe AIR, which is my target. I'm
trying to put some panes into an AccordionContainer like so:
var mainview = dijit.byId("mainview");
var rand = randomString();
var widg = gtd_create_entry_widget(rand)
air.trace(mainview);
air.trace(widg);
mainview.addChild(widg);
"mainview" is my AccordionContainer, and gtd_create_entry_widget() is:
function gtd_create_entry_widget(id) {
var entry = new dijit.layout.ContentPane();
entry.attr("id",id);
entry.attr("title","title "+id);
return entry;
}
The pane shows up in the container, with the correct id and title, and
no errors, however, if I try to add another pane, the next one shows
up too, but I get the error:
TypeError: Result of expression '_7' [undefined] is not an object.
I get the same error if I run
var mainview = dijit.byId("mainview");
mainview.destroyDescendants();
and also, only one pane is destroyed at a time, and I understand this
method should destroy all the children.
I can include full project code if required.
Thanks a lot

I'm not exactly sure if this is going to fix your problem, but you're supposed to use dijit.layout.AccordianPane (http://www.dojotoolkit.org/api/dijit/layout/AccordionPane.html) with the AccordianContainer.
What would be the best way to go about building an Adobe AIR app that doesn't have any windows (i.e. exists only in the system tray / dock)? I noticed that the default base tag in Flash Builder is <s:WindowedApplication> which seems to imply there'll be a window.
Should I just use <s:WindowedApplication> and call window.hide()? I saw there's another base class, <s:Application>, but I got the sense that was more for files that run in the browser. It seems like using window.hide() would briefly flash a window when the application starts which could confuse users. However I'd also ideally like to retain the ability to have the app open a window later if needed, or also to change the application from tray-only to windowed through an update.
You need to edit the app-config file to enable transparent chrome and visible = false. Then you need to change the WindowedApplication tag to and app your custom skin. You need to add control buttons for close etc, since that functionality isn't present in a web-app (since you have changed the tag). Also you need to add drag functionality. If you like to make your application re-sizable you need to add that too, manually.
In your manifest (-app.xml) file set systemChrome to none and transparent to true. The visible property is irrelevant, and the default is false anyway so ignore it.
you'll have to tweak this, import whatever classes are missing, etc... you could also do it as an mxml component and just set visible and enabled to false on the root tag. Fill up the trayImages array with the icons you want in the dock.
