I can't think of a reason why your tree wouldn't display. I still
think the most likely is that the "value" attribute is null b/c this
causes the encodeChildren method to return without warning (something
to be fixed in the future.) Any other problem and I would expect an
exception thrown somewhere.
You mentioned that your jsp is identical to tree2.jsp. How is that
possible? Tree2.jsp has facets that are specific to the data for that
example. Unless your data is returning the same values for getType on
the nodes as they are in the examples, this won't work. I would say
that is the source of your problem but when this happens, you should
get an IllegalArgumentException.
Why don't you post your code and jsp if you continue to have problems?
We're still working on the documentation for the components so its
understandable if there is some confusion right now. :-)
