Question

I also called listener "beforeclose" and in this method destroy tabpanel but that doest not work.

What can be done?

Answer 1

Are you sure that closeAction option is set to destroy?
Of course it is a good idea to show simplified sources, so we can understand where the problem exists.

Answer 2

Add closeAction:'destroy' to your window. It should work.
