Description Thomas Preisler 2007-07-31 00:31:05 UTC 
I'm getting the following assertion error when running cnd 6.0 (with NB6.0):
java.lang.AssertionError
	at org.openide.text.CloneableEditorSupport.getOpenedPanes(CloneableEditorSupport.java:868)
	at org.netbeans.modules.cnd.modelutil.CsmUtilities.getCsmFile(CsmUtilities.java:213)

	at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:539)
[catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:964)

The problem may not be in CND. Please evaluate our code and verify we are correctly using the API. If we are, I will
refile the bug against NB.
Comment 1 Thomas Preisler 2007-07-31 00:45:39 UTC 
From Ivan:
It's this one:
	assert SwingUtilities.isEventDispatchThread(); // NOI18N
It is a valid asertion and is definitely a dbxgui (or other client of
editors) problem.
Comment 2 ivan 2007-08-02 03:31:31 UTC 
For dbxguis part:
        This assertion checks to see if the function,
        CloneableEditorSupport.getOpenedPanes() is called on the AWT EventQ.
        This function plays a crucial role in all NB idioms for getting
        information from the editor:
        http://wiki.netbeans.org/wiki/view/DevFaqFindCaretPositionInEditor

        dbxgui access this through a utility class EditorBridge.
        It's easy to check all places where EditorBridge is used and all of
        them seem to be already on the eventq ... except default actions
        based on ActionsProviderSupport.

        Since all such dbxgui actions have a base class NativeActionsProvider
        it's easy to have NativeActionsProvider override postAction() and
        directly call doAction() instead of letting the default implementation
        route it through a request processor.
