Hi All,

I have a grid which has 2 Ext.ux.CheckColumn with another Grid column.
On loading the user preferences(JSON obj from server), i have to check the checkboxes which was saved earlier.
Now after clearing the form(i do store.removeAll()), If i expand the grid panel again i am make another ajax call to retrieve data and show the grid data without user saved preferences(ie.., without check column checked).
Issue is i am still seeing the checkbox checked in checkcolumn

what other configutaion i need to use to destroy the store state, or
Note: I have not used any extra configuration apart from width, store or id , statefull is false.

can somebody help...
