the getter of the TreeState is imho the wrong place to capture the selection.
this should be done in the action method werd the result is stored.
the way you do this is ok, but you will get the selection before
rendering, not the one after submitting the page.

Now, it display the checkbox on the tree that was being selected, but
when I unchecked one of the leafs or event try to resaving it. The
treestate never get never pick up the leafs that was being checked. Am
I doing something wrong? This is how I tried to capture? Thanks.
/**
* @return the _selectedCategories
*/
public TreeState getSelectedCategories() {
Set<DefaultMutableTreeNode> selection =
_selectedCategories
.getSelection();
boolean empty = selection.isEmpty();
if (!empty) {
_categoriesSelection.addAll(selection);
}
return _selectedCategories;
}

Hi,
just add all nodes which should displayed as selected to the selected
set in the treeState:
selectedTrees.getSelection().add(node);
