Re: StackOverflow caused by TreeView#wlpc
Fortunately, I could solve the issue in the mean time after breaking it all down to new AbstractNode(Children.LEAF); My Problem was that I was using the wrong Lookup. I'm not knowledged enough to judge whether this is just misuse or a case which could be prevented by NB. The Code I was basing this off is: https://github.com/jMonkeyEngine/sdk/blob/master/jme3-materialeditor/src/com/jme3/gde/materialdefinition/navigator/MatDefNavigatorPanel.java#L127 I changed that line to mgr.setRootContext(new MyNode(lookup)); though, but that shows the issue, I had to use new MyNode(data.getLookup()); "lookup" is not the lookup wanted anyway, but I wonder why that could trigger an endless recursion, maybe because of the "ContextListener" calling updateData? Or is this related to ExplorerUtils.createLookup?

Hey Guys, So this issue is on Netbeans 8.2, I cannot test them with NB 9.0 yet as I have other issues preventing an upgrade. I am also talking about the Netbeans Platform Facility here, not Netbeans itself. I tried adding Properties Support by adding a Navigator with the Nodes API, which works so far (I can see the Nodes in the Navigator panel). The Problem is that selecting a Node in the Navigator leads to a StackOverflowException because TreeView's Weak PropertyChangeListener (that's my finding so far, the debugger only shows that it's a WeakListenerImpl) and EMLookup/ProxyLookup hang at ArrayList#addAll() because it calls Collection#toArray, which in turn calls addAll at some point. java.lang.StackOverflowError at org.openide.util.lookup.ProxyLookup$LazyCollection.getComputed(ProxyLookup.java:1306) at org.openide.util.lookup.ProxyLookup$LazyCollection.computeDelegate(ProxyLookup.java:1116) at org.openide.util.lookup.ProxyLookup$LazyCollection.delegate(ProxyLookup.java:1090) at org.openide.util.lookup.ProxyLookup$LazyCollection.delegate(ProxyLookup.java:1073) at org.openide.util.lookup.ProxyLookup$LazyCollection.size(ProxyLookup.java:1158) at org.openide.explorer.DefaultEMLookup$NoNodeLookup$ExclusionResult.allItems(DefaultEMLookup.java:254) at org.openide.util.lookup.ProxyLookup$LazyCollection.computeSingleResult(ProxyLookup.java:1296) at org.openide.util.lookup.ProxyLookup$LazyCollection.computeDelegate(ProxyLookup.java:1123) at org.openide.util.lookup.ProxyLookup$LazyCollection.delegate(ProxyLookup.java:1090) at org.openide.util.lookup.ProxyLookup$LazyCollection.delegate(ProxyLookup.java:1073) at org.openide.util.lookup.ProxyLookup$LazyCollection.toArray(ProxyLookup.java:1179) at java.util.ArrayList.addAll(ArrayList.java:581) at org.openide.util.lookup.ProxyLookup$LazyCollection.computeDelegate(ProxyLookup.java:1143) at org.openide.util.lookup.ProxyLookup$LazyCollection.delegate(ProxyLookup.java:1090) at org.openide.util.lookup.ProxyLookup$LazyCollection.delegate(ProxyLookup.java:1073) at org.openide.util.lookup.ProxyLookup$LazyCollection.size(ProxyLookup.java:1158) at org.openide.explorer.DefaultEMLookup$NoNodeLookup$ExclusionResult.allItems(DefaultEMLookup.java:254) at org.openide.util.lookup.ProxyLookup$LazyCollection.computeSingleResult(ProxyLookup.java:1296) at org.openide.util.lookup.ProxyLookup$LazyCollection.computeDelegate(ProxyLookup.java:1123) at org.openide.util.lookup.ProxyLookup$LazyCollection.delegate(ProxyLookup.java:1090) at org.openide.util.lookup.ProxyLookup$LazyCollection.delegate(ProxyLookup.java:1073) at org.openide.util.lookup.ProxyLookup$LazyCollection.toArray(ProxyLookup.java:1179) at java.util.ArrayList.addAll(ArrayList.java:581) With a Breakpoint on addAll I could see that it happens in PropertyChangeSupport#fire() with a selectedNodes event. Now since my code is really simple (actually only extending AbstractNode and using the ChildFactory), I am unsure how to proceed/try to debug. Also this kind of error has been seen on the issue tracker: https://netbeans.org/bugzilla/show_bug.cgi?id=210689 (the exception is only different since we have enough RAM) Is there a way to find out what the fuzz is about those Lookups? Could that be related to my code doing something wrong? or not registering something to the lookup? Is there a workaround to use the Properties Panel without Nodes? (as that's essentially what I need, I already have a graphical representation of the contents of the Navigator) Thanks in Advance, Marc Streckfuß - To unsubscribe, e-mail: users-unsubscr...@netbeans.apache.org For additional commands, e-mail: users-h...@netbeans.apache.org For further information about the NetBeans mailing lists, visit: https://cwiki.apache.org/confluence/display/NETBEANS/Mailing+lists
