Yahor Radtsevich resolved JBIDE-6204.
-------------------------------------

    Resolution: Done
      Assignee: Jiri Peterka  (was: Yahor Radtsevich)


RESOLVED in both trunk and 3.1.x branch.

The reason was a NPE after a call of org.eclipse.ui.IWorkbenchWindow.getActivePage(), which may be null if the page is not initialized. This statement was replaced by a call of org.eclipse.ui.part.WorkbenchPart.getSite().getPage() . Also see http://www.eclipse.org/forums/index.php?t=msg&th=156906 .

> STEPS TO REPRODUCE:
> 1. Close all opened files in Eclipse.
> 2. Open file 'trunk\jsf\tests\org.jboss.tools.jsf.vpe.jsf.test\resources\jsfTest\WebContent\pages\components\commandButton.jsp' in VPE
> 3. Close Eclipse.
> 4. Run eclipse again.
>    ACTUAL RESULT:
>    commandButton.jsp is opened in VPE and its visual representation is empty (see screenshot-1.png).
>    EXPECTED RESULT:
>    The visual representation is rendered by VPE.
> NOTE: If after these steps user clicks on the empty area in VPE, the Eclipse may crash with an error in xul.dll (see hs_err_pid4268.log).
