Hi. I load up a treepanel successfully in both FF and IE.
I can reload it firefox, but not IE - it just closes to the root node with no child nodes - anybody got any ideas?
(Sometimes, it will work for a random number of times, and then just stop working)

Code:
            


this.getLoader().load(this.getRootNode());   
            this.getRootNode().expand();

here's my json:
[{"text":"UserCom1","leaf":false,"cls":"folder","children":[{"text":"UserCom","leaf":true,"id":"1"}]},{"text":"Frequency","leaf":false,"cls":"folder","children":[{"text":"H","leaf":true,"id":"2"}]}]
