User Cache issue when update logic in AX 2009

You may into a situation when you need to update a change in a form in AX 2009 in production environment, and for some reasons, one or more users do not see the changes even after you restart AOS service, clear their user cache.
The solution is to make the user admin in AX, go to the object that needs to be updated, compile and restore to get the latest changes. Test to make sure the change is now applied to them. Revoke the Admin permission, done.
