Shenghao Fang commented on GERONIMO-6103:
-----------------------------------------

It's caused by the null value of the tree store. The tree store is not 
constructed since it is constructed in the 'callback' function of DWR. The 
'callback' function is called by DWR once the requested tree data is 
transferred from the server. The remote call is asynchronized, so the tree may 
be constructed before the tree store has been constructed that leads to the 
null value issue.
