Refresh a BaseTree?

[Kaspar Fischer <hb...@rapsak.com>]

I create a BaseTree like this:

   final DefaultTreeModel model = new DefaultTreeModel(...);
   IModel< new AbstractReadOnlyModel<TreeModel>()
     {
       @Override
       public TreeModel getObject()
       {
         return model;
       }
     };
   add(new BaseTree("tree", model) { /* ... */ });

When the user clicks a certain link (outside the tree), I change some  
data that affects the tree and want the tree to get recreated. How can  
I achieve this?

I tried BaseTree#updateTree() with no success. Also,  
BaseTree#setDefaultModel(new DefaultTreeModel(...)) doesn't work; the  
tree becomes empty.

Any ideas?

Thanks,
Kaspar
