I have encountered the same problem with HtmlTree.addToModelListeners.
Basically I am trying to display the contents of an XML Document using the original HtmlTree. but for some reason, the tree won't refresh when a new XML Document is available. So I thought I could get it to work by removing the old tree entirely from the panel, and then insert a new one. Then I got a nullPointerException when
HtmlTree.addToModelListeners is invoked... yet the document doesn't give anything on what this method is doing.
Please help. Thanks.
