Hi,

I have a problem to "clear my tree".

Typical tree (visible as is):

top --- node1 --- leaf1
     |          |- leaf2
     |
     |-- node2 --- leaf3
                |- leaf4

User has node1 selected and click a RadioButton.
Now I want to collapse the tree so that top and node1 and node2 are visible.

I have tried with:
       TreePath top = tree.getPathForRow(1);
       tree.fireTreeCollapsed(top);
       tree.setSelectionRow(0);

Problem is that leaf3 & 4 are still visible

If I try with row=0 only top is visible. I then tried to expand on row=1 
but nothing happened.

Any hints?
