Comment 4 Andrew Korostelev 2009-11-03 09:55:49 UTC 
It seems that this issue is caused by issue 17559o.
The only change I see reasonable to do on fx side is to block NPE to have the same behavior as in other modules.
Comment 5 Andrew Korostelev 2009-11-03 11:20:57 UTC 
NPE is blocked.
changeset:   2843:a121e3d4a3a2
the rest should be done on issue 175590 side.
Comment 6 mslama 2009-11-04 17:46:52 UTC 
What editor support do you use?
Comment 7 Andrew Korostelev 2009-11-05 10:51:41 UTC 
We have invoked CloneableEditor.componentShowing() from MultiViewElement.componentShowing() implementation, as expected.
But before component is ready to show, we have invoked CloneableEditor.getEditorPane() for wrapping purposes.

I have added componentShowing(); invocation before getEditorPane().
It works now.
