My data isn't changing. This only manifests itself
when I'm using the server-side tree, BTW. Client-side
everything works peachy.

I don't think it has to do with any mutation in the tree. I think that
the
isNodeSelected method is simply being called before the nodeId has
been set
on the object. It gets called again later when the nodeId is set. I
tested
the fix I put in the bug report and it had no side effects. The
processing
of the jsp page must iterate over the tags a number of times and in the
early iterations the components are not yet fully initialized.

Are we sure that is it? This would imply that the structure of his
tree is changing between posts. That was the problem in MYFACES-160
but you had a pretty unusual case where you simulating the tree
changing between *every* post.
Jon, does this sound like it applies to you? Is your data changing
between posts?

This is the bug I reported about isNodeSelected() throwing a
NullPointerException because getNodeId() returns a null nodeId.

I put the fix in the bug report. It's null because it hasn't been set
yet.

I still need some time to think about what the problem might be. I
have a lot of personal stuff going on that's keeping me busy at the
moment. Plus I am working on some stuff related to the new website,
etc.
I will get back to you shortly though.

Ack!
Replace 'false' with null (hence the NPE).
The NPE occurs in HtmlTree.isNodeSelected() -- it
does:
return getNodeId().equals(_selectedNodeId)
getNodeId() returns false. Up the stack, this
is being called from DebugUtils.printComponent.

Jon,
When you say getNodeId returns false, do you mean the string value
"false"? That method returns a String so I'm a bit confused. How
do
you know the id is "false"? Are you doing a debug statement?
Please clarify so I can try and help you. Also, what is the exact
line where the NPE occurs? Is it the return statement in
isNodeExpanded? If so (and if you have a debugger) it would be
helpful to know which value is null.

Hey Sean,
Hope this isn't a braindead question, but:
I'm getting a NPE in the tree2 code when there is
no node that is selected & I am expanding/collapsing.
Basically it comes about when HtmlTree.isNodeSelected
is run -- getNodeId() returns false, then kaboom.
Thoughts?
