Description

Steps to reproduce:

• Create a component extending FormComponentPanel and use a wicket:enclosure in it
• Create a component "MyTab" extending Panel with a form which includes component above
• In your page, add an AjaxTabbedPanel with two tabs and add "MyTab" twice

When changing tabs the exception shown below is thrown.

The problem occurs with both 7.0.0-M4 and 7.0.0-SNAPSHOT

I am also attaching a quickstart to reproduce the problem.
