Comment 1 Tomas Zezula 2013-06-13 18:43:44 UTC 
Unfortunately the ClassMemberPanelUI.propertyChange() has to modify the Lookup outside the EDT because the InstanceContent.add() may be expensive, see issue #223978 for details. It's questionable if the  NodeAction$DelegateAction.resultChanged() should be prepared that events from lookup outside of the EDT.
