Sean,
After altering the order I constructed the "tree2" it worked! Added the parents then the children as I went along. Rather than constructing branches as I went along and adding the completed branch to the parent. If that makes sense?
This is reverse to how I did it in Web Galileo.
Feel you could do with some more warning/error messages though as it was fixed more by luck than judgement.
Regards,
Roger Lee

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. :-)

Yes my "backer" class does that. I have also taken the backer class
(TreeBacker.java) from the examples and used that. Still nothing displays.
My JSP is identical to tree2.jsp.
> 1.) Your tree has a rendered attribute of false
Where would this be set?
