hello everyone i have this scenario:

  1. 1 tree (simpletreemodel)
  2. listbox

i would like drag listitem of my listbox in tree to build it. when i drop listitem in tree fires event but get object dragged empty maybe it happens because i have 2 different component

public void onEvent(Event event) throws Exception {
    if (event instanceof DropEvent) {
        DropEvent de = (DropEvent) event;
        ListItem item = (ListItem) de.getDragged();

I think u can add the selected item to the tree and remove it from the list like:

public void onEvent(@BindingParam("event") final Event event)
{
  treeModel.add(event)
  listModel.remove(event)
}
