Yes originally nothing was been shown in the JSP.
The rendered HTML only had the < head > < title > showing. Even a heading inside a < verbatim > wasn't appearing.
Maybe it was cached earlier version. The populated tree did suddenly appear!
Anyway thanks for all your help and suggestions.
Regards,
Roger

Subject: Re: x:tree2 problem - Fixed
Roger,
I looked at the code that you sent me offlist. I'm glad you got everything working but your explanation of what solved the problem seems a bit odd. Originally you were reporting a blank page right? That is to say, *absolutely* without even a root node right?
As I said earlier that seems to only be possible if the root node is null (and yes we should add a warning there.) Yet your code seemed to have created a non-null root node in its call to createTreeStructureLoanSelection. Even if the order in which children added affected things, it still wouldn't change the fact that your root node is not null.
Actually, I thought of one other situation where your tree could be blank. That would be if there was no visible HTML rendered inside of the appropriate facets. I checked your JSP and you have a facet for the "loanHierarchy" type so I don't understand how you could possibly have gotten a blank page. I would have expected an emtpy root folder (that couldn't be expanded) at a *minimum.*
Are you sure you didn't experience something like this instead? If not, then possibly you were running off a cached version of the component tree or something?

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.
