Description _ pcw 2007-04-30 00:23:21 UTC 
I got this trace with a current NB 6 build.  No clue what the trigger was but
I've never seen it before.

java.lang.ClassCastException: org.netbeans.modules.palette.PaletteItemNode
cannot be cast to org.openide.nodes.Node$Cookie
        at org.openide.loaders.XMLDataObject.getCookie(XMLDataObject.java:302)
        at org.openide.loaders.DataNode.getCookie(DataNode.java:397)
        at org.openide.nodes.NodeLookup.addCookie(NodeLookup.java:76)

 ... see attached for the rest

Comment 2 Stanislav Aubrecht 2007-05-02 13:52:42 UTC

jdk version?
Comment 3 Sergey Petrov 2007-05-24 10:29:57 UTC 
I'm able to reproduce by following steps from
http://platform.netbeans.org/tutorials/nbm-palette-api3.htm (but on my project
and on new empty module project too)
reproducible with 070523, not reproducible in 5.5

steps:
0. create netbeans module project
next from tutorial, but change folder to folder in your ptoject:
   1. Right-click the project, select New -> File/Folder... Choose XML under
Categories then XML Document under File Types. Click Browse... and select
src/com/example/palette (Click Select Folder). Click Next.
   2. In the Name and Location panel, type simple-item for the File Name. Click
Next.
   3. In the Select Document Type choose DTD-Constrained Document. Click Next.
   4. In the DTD Options, choose from the list for DTD Public ID
-//NetBeans//Editor Palette Item 1.0//EN. Select editor_palette_item for the
Document Root. Click Finish. 

exception is thrown, and is thrown again each time xml node is selected in
project tree, 
generated xml contains 'null' instead of correct link to dtd.

Why the issue is marked for 'future'?

Each click, each save each modification with element_node xml followed by
exception, can't open xml after ide restart =>P1

Comment 6 Sergey Petrov 2007-05-25 13:39:28 UTC 
Ok, I don't see ClassCastException any more, but not sure if I should verify the
issue

Still have minor problem with opening: can't open with doubleclick, but can use
context menu Edit now, may be I'll file separate issue later if not yet filed
