I was trying to implement lockable feature on tree.Panel so i borrowed from grid.Panel

Ext.tree.Panel(Ext.grid.Panel, ['bothCfgCopy','normalCfgCopy','lockedCfgCopy']);

but now my grid columns are objects i.e a column.$className on a tree.Panel would return an object because they have been transformed. How do i hide columns now as all functionality such as hide(), setVisible() have been lost ?

Thanks in advance

It might not still be relevant, but here's an example of a buffering locking grid.

You can set buffering to false and use as is, or you can use it as a guideline for you current implementation.
