Bug 322167

Build Identifier: 20100617-1415

After making changes in my editor I click the Save button (ActionFactory.SAVE).  It invokes my overridden doSave() with no errors.  But then I receive the following exception and my editor is still marked as dirty.

java.lang.NullPointerException
	at org.eclipse.jface.action.StatusLineManager$1.isCanceled(StatusLineManager.java:176)
	at org.eclipse.ui.internal.SaveableHelper$4.run(SaveableHelper.java:267)
	at org.eclipse.jface.operation.ModalContext.runInCurrentThread(ModalContext.java:481)

	at org.eclipse.ui.internal.WorkbenchWindow.run(WorkbenchWindow.java:2540)
	at org.eclipse.ui.internal.SaveableHelper.runProgressMonitorOperation(SaveableHelper.java:273)
...

If I modify the method new IProgressMonitorWithBlocking().isCanceled() in StatusLineManager.getProgressMonitor() to check for null, then this problem goes away.  A workaround to this issue is to display the status line manager.

Reproducible: Always

Steps to Reproduce:
1.  Create a simple RAP application and hide the status line manager
2.  Modify something in the text editor and click Save
