Comment 1 Jaroslav Tulach 2012-09-17 09:58:32 UTC 
This report is about XML module's DataObject. The only idea I have is to use FilterNode. Create a generic one in createNodeDelegate and schedule a refresh for later.
Comment 2 Martin Balin 2015-09-17 14:09:51 UTC 
Report from old NetBeans version. Due to code changes since it was reported likely not reproducible now. Feel free to reopen if happens in 8.0.2 or 8.1.
