Throw PrincipalException while Activate user in IE9 Only

[Nisarg Parikh, modificado hace 12 años.]

Hi All,

I am using Liferay 6.0.6 CE.

Scenario is
-Deactivate any user.
-Search that user
-Click on "Activate" from action button
- It throws PrincipalException exception. If we click on "Restore" button, it will work.

It works in all other browsers IE8, FF, Chrome..
Any idea why is this happening in IE9?

Please help me.
Thanks in Advance.
