hi gxt users,

I have created an editable grid with only 3 columns out of 5 as editable.
i need to retrieve the number entered in these editable cells and add them to display in the other cells of same grid. ive added a storeListener to the ListStore that contains preloaded grid data. and overriden storeUpdate(StoreEvent<BaseModel> se) method. but im not getting how to retrieve the updated data using this update event.... pls help me guys.......
the code is like this
