Comment 2 Andrew Korostelev 2009-11-03 15:35:04 UTC 
most likely it is caused by common issue 175590
While not sure, set as 'depends on', but not duplicate.
Comment 3 Karol Harezlak 2009-11-03 17:29:13 UTC 
Since we did not change anything in this part of the code for this 6.8 it looks like problem on platform side.

Comment 4 Petr Suchomel 2009-11-04 09:09:47 UTC 
Marku, I think this is an optimization issue which was rounding around for a while.
Comment 5 mslama 2009-11-04 12:44:10 UTC 
I am looking at it. Seems the same as issue #175590.
Comment 6 mslama 2009-11-04 13:04:34 UTC 
You must call CloneableEditor.componentShowing. Form editor does it as follows:
at org.openide.text.CloneableEditor.componentShowing(CloneableEditor.java:208)
at org.netbeans.modules.form.FormEditorSupport$JavaEditorTopComponent.componentShowing(FormEditorSupport.java:1240)
at org.netbeans.core.multiview.MultiViewPeer.showCurrentElement(MultiViewPeer.java:295)
at org.netbeans.core.multiview.MultiViewPeer.showCurrentElement(MultiViewPeer.java:265)
at org.netbeans.core.multiview.MultiViewPeer$SelectionListener.selectionChanged(MultiViewPeer.java:676)
at org.netbeans.core.multiview.MultiViewModel.fireSelectionChanged(MultiViewModel.java:243)
at org.netbeans.core.multiview.MultiViewModel.setActiveDescription(MultiViewModel.java:115)
at org.netbeans.core.multiview.MultiViewModel$BtnGroup.setSelected(MultiViewModel.java:293)
at javax.swing.JToggleButton$ToggleButtonModel.setSelected(JToggleButton.java:237)
at javax.swing.ButtonGroup.setSelected(ButtonGroup.java:147)
at org.netbeans.core.multiview.MultiViewModel$BtnGroup.setSelected(MultiViewModel.java:289)
...

This change was done in CloneableEditor to fix semantics of CloneableEditor.close.
