I've been playing around with the Treenode widget and I have a problem. I
build 2 trees dynamically from data pulled from a database. That works
great. But when I try to add a selected child from one tree to the other, it
does nothing. I don't get an error but the new node doesn't show up in the
other tree. Anyone?
The code recurses the tree to find where it has to start adding from.
