Hi all,
I added a SelectionHandler to my tree. If a leaf if selected, an other
Event should be fired. If the users selects an node with childs, the
branch should be opend (if it's state is false) or (closed if state is
true). Selecting a leaf works fine. Opening an branch works fine too.
If a branch is opend, the event is fired twice, and the branch is
closed and opened immediately.
Is it a bug? In GWT Version 1.1.0 was a bug fixed concerning Events on
Trees (I'm using GWT 1.6.4). Or have I an error in reasoning?
My code looks like this:
public void onSelection(SelectionEvent<TreeItem> event) {
TreeItem item = event.getSelectedItem();
if(item.getChildCount() == 0) {
controller.navigationChanged(item);
}
else {
item.setState(!item.getState());
}
}
Thanks for responses
