>                 URL: http://jira.jboss.com/jira/browse/JBIDE-2074
>             Project: Tools (JBoss Tools)
>          Issue Type: Feature Request
>          Components: Visual Page Editor
>    Affects Versions: 2.1.0.beta1
>            Reporter: Snjezana Peco
>         Assigned To: Maxim Areshkau
>            Priority: Minor
>             Fix For: 2.1.0.CR1

>
> The following code causes NPE in JUnit tests: 
> // Wait while visual part is loaded
> Display.getCurrent().syncExec( new Runnable() {
> 	public void run() {
> 		while( Display.getCurrent().readAndDispatch() && getController()==null) {
> 	        }
> 						
> 	}
> });
> I have got the exception in the testJbideMultiple test and in some other tests.
> VpeTest.java, line 153
> XulRunnerEditor xulRunnerEditor = vpeController.getXulRunnerEditor();
> vpeController is null because the above mentioned code doesn't work correctly.
> The Display.getCurrent().readAndDispatch() reads and dispatches events and returns false if there isn't any. 
> It isn't related to loading page in the XULRunner browser.
> The correct code that waits for the page has been loaded is the following:
> loaded = false;
> xulRunnerEditor.getBrowser().addProgressListener(new ProgressListener() {
> 	public void changed(ProgressEvent event) {
> 	}
> 	public void completed(ProgressEvent event) {
> 		loaded = true;
> 		xulRunnerEditor.getBrowser().removeProgressListener(this);
> 	}
> 				
> });
> xulRunnerEditor.setURL(INIT_URL);
> // Wait while visual part is loaded
> while (!loaded) {
> 	if (!Display.getCurrent().readAndDispatch())
> 		Display.getCurrent().sleep();
> 	}
> Max, would you like me to commit this code?
