Nazdar, when i expand a query in my Local Repository in the Dashboard, the AWT thread gets busy and repaints the dashboard on and on until i collapse the query. See the snapshot

Comment 2 Ondrej Vrabec 2012-05-07 07:37:39 UTC 
If i understand it correctly then the reason is:
TreeListNode.getRenderer is called with this.renderer set to null -> this.renderer gets initialized and renderer.configure is called -> TaskNode.getComponent is called from inside the configure method -> TaskNode.fireContentChanged() which in turn sets TreeListNode.renderer to null and triggers repaint. And this goes on and on.

fixed as part of http://hg.netbeans.org/core-main/rev/7cdb5ea9d86a - useless fireContentChanged() call removed
