(NetBeans Q-Build 200303202210) (TaskList 0.9.0 beta 1) (J2SDK1.4.1_02) Something simliar to the category node closing/opening bug happened. From then on, every few keystrokes in the java editor, a NullPointerException pops up. (Very annoying). Restarting netbeans did not seem to help. *********** Exception occurred ************ at Wed Mar 26 16:11:12 CET 2003 java.lang.IllegalStateException: VisualizerNode.getChildAt() returning null! at org.openide.explorer.view.VisualizerNode.getChildAt(VisualizerNode.java:207) at javax.swing.tree.DefaultTreeModel.getChild(DefaultTreeModel.java:156) at javax.swing.tree.VariableHeightLayoutCache$TreeStateNode.expand(VariableHeightLayoutCache.java:1466) at javax.swing.tree.VariableHeightLayoutCache$TreeStateNode.expand(VariableHeightLayoutCache.java:1270) at javax.swing.tree.VariableHeightLayoutCache.rebuild(VariableHeightLayoutCache.java:725) at javax.swing.tree.VariableHeightLayoutCache.treeStructureChanged(VariableHeightLayoutCache.java:626) at javax.swing.plaf.basic.BasicTreeUI$TreeModelHandler.treeStructureChanged(BasicTreeUI.java:2469) at javax.swing.tree.DefaultTreeModel.fireTreeStructureChanged(DefaultTreeModel.java:561) at javax.swing.tree.DefaultTreeModel.nodeStructureChanged(DefaultTreeModel.java:345) at org.openide.explorer.view.NodeTreeModel$Listener.reordered(NodeTreeModel.java:152) at org.openide.explorer.view.VisualizerChildren.reordered(VisualizerChildren.java:168) at org.openide.explorer.view.VisualizerEvent$Reordered.run(VisualizerEvent.java:175) at org.openide.explorer.view.VisualizerNode$QP.run(VisualizerNode.java:466) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:178) at java.awt.EventQueue.dispatchEvent(EventQueue.java:448) [catch] at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:197) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:150) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:144) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:136) at java.awt.EventDispatchThread.run(EventDispatchThread.java:99) *********** Exception occurred ************ at Wed Mar 26 16:11:20 CET 2003 java.lang.NullPointerException at org.openide.explorer.view.TreeTableView$14.compare(TreeTableView.java:930) at java.util.Arrays.mergeSort(Arrays.java:1237) at java.util.Arrays.sort(Arrays.java:1185) at java.util.Collections.sort(Collections.java:151) at org.openide.explorer.view.TreeTableView$SortedNodeTreeModel.sortChildren(TreeTableView.java:1013) at org.openide.explorer.view.TreeTableView$SortedNodeTreeModel.nodesChanged(TreeTableView.java:1099) at javax.swing.tree.DefaultTreeModel.nodeChanged(DefaultTreeModel.java:261) at org.openide.explorer.view.NodeTreeModel$Listener.update(NodeTreeModel.java:160) at org.openide.explorer.view.VisualizerNode.run(VisualizerNode.java:344) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:178) at java.awt.EventQueue.dispatchEvent(EventQueue.java:448) [catch] at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:197) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:150) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:144) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:136) at java.awt.EventDispatchThread.run(EventDispatchThread.java:99) After closing all tasklist windows the NullPointerException changes but continues to popup every few keystrokes in the java editor.

Can you please upgrade to the latest version of the modules? I recently (after the module version you're reporting) fixed a race condition bug where occasionally, suggestion scanning will occur even when the suggestions view is not visible (which it's not supposed to do).
I will mark this one as fixed. If you run into something similar with current bits, please file a new issue. Thanks for your help!
sorry for the lack of response. (was busy moving house :) ) yes, with the latest version I do not get this anymore. although something similar is happening, i will file it separately as requested.
