In UserPortal ,user can only see his own permissions on the objects. User has to be able to see all permissions associated with the object. For example: user leonid that has VmCreator permissions creates VM "test" user leonid goes to permissions tab of created VM "test" and wants to give to user einav diskCreator permission on his VM. addPermission succeeded but ortal's permission not shown in permission tab e.g. after clicking "ok" button nothing happens. When user einav logs in and goes to vm "test", she can see her permission on this VM but can't see leonid's permissions.
in other words user has the right to give permissions to another users but has no right to see what permissions he just gave.
