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);
