I'm using the reconfigure method of Ext.grid.Panel to switch between two stores in a grid. The load mask on the initial store works correctly, but no load mask is displayed for the second store.
See jsFiddle here: http://jsfiddle.net/Esfu4/
When you hit the button to switch to Store 2, no load mask appears, even when you refresh afterwards.
If you look at the jsFiddle here (http://jsfiddle.net/H8U3E/), where the two stores are reversed, the load mask works correctly.
Trying to figure out how to get the load mask to work in the first jsFiddle.
