Adding a node with a TreeViewer; what's wrong?

Hi,

This is a more concise version of a previous post.

This code in a TreeViewer event listener:

insert(((TreeSelection)getSelection()).getFirstEle ment(), newElement, 0);
refresh();
System.out.println("Added new element");

prints the message but doesn't add a node to the tree. Any hints why?

Thanks.

Rodrigo

I am puzzled as to why I have not received any replies. I would think that inserting a node to a tree is something pretty much anyone using TreeViewer would have to be able to do, no?

Best,

Rodrigo
