I have Treepanel with "OnReadData" data loading.
When user click to expand node, children data is loaded. That is ok.

But, I want to refresh children after database update and dont know how.
When I use store.reload() it runs "OnReadData" event but with wrong parent node (e.NodeID is wrong, usually previously used).
When I use storeLoadProxy() it runs "OnReadData" event but with root as parent

How to call "OnReadData" function and specify parent NodeID so it load its children data, just like first click on expand do?
