Thanks, but that is not exactly what I am trying to figure out. Maybe my 
explanation of what I am looking for, was to short. Sorry for that.

 From a catalog search I retrieve a list of objects, which all have a 
method that I can use for accessing the branches. My problem is how to 
properly construct a root element, that stays accessible while a user 
expands and collapses the branches of the tree.

I suppose I have to wrap the list, resulting from the catalog query, 
into a temporary, session based object. This wrapper should have the 
same child access method, as the objects resulting from the catalog query.

It should then be possible, to construct a tree with the temporary, 
wrapped list as root object.

Is there an easier way, or can anyone point me to an example, where this 
had been realized?

Thanks
Bories
