Extjs 3.4 Grid's store undefined after reconfigured

I have an issue when reconfigure a grid panel. I have a EditorGridPanel which its store is built from a custom columnModel

After saving new settings (decide to show or not show some columns), I get a new store and a new column model, then I call reconfigure function to reconfigure the Grid, like this:

grid.reconfigure(newStore, newColumnModel);

The reconfigure function worked well, but when I click in the checkbox (CheckboxSelectionModel) to select a row, I see this error "Cannot read property 'store' of undefined"

I work on ExtJS 3.4. On their API page http://docs.sencha.com/extjs/3.4.0/#!/api/Ext.grid.GridPanel-method-reconfigure, they warned:

"Be aware that upon reconfiguring a GridPanel, certain existing settings may become invalidated. For example the configured autoExpandColumn may no longer exist in the new ColumnModel"

What should I do in this case to make the CheckboxSelectionModel work as before reconfiguring?

Thanks for your help!

You need to do some debugging or provide where that error is happening. Please provide more information on that error.
