there is the pretty good Ext.grid.Panel object and it contents an Ext.data.Store object,
The Ext.data.Store object has got the beforeLoad event, a loading mask, the (after)load event and the isLoading() method.
But where are a syncing mask, (after)sync event, and an isSyncing() method?
Why I cannot inject my (request-)parameters in the beforesync-event, like I do it in the beforeload-event?
I want to show a loading mask when I do save my changes in the grid, if I call the me.getStore().sync() method.
Also I want to avoid users re-loading my grid if it is syncing. But I don't have isSyncing() or another method to check it out in the load-button-handler!
