Tree onBeforeLoad get selected

[devnull]

This always seems to return null, even if a tree node is selected:

Code:

    onBeforeLoad: function(node,param){
      var sel = $(this).tree('getSelected');
      console.log('selected:'+sel);
    },

If a tree node is selected, the getSelected method returns this selected node. Please check if no nodes are selected.
