Problem with editing repos in profile in WebUI

[Leonid Flaks]

I run into this situation: I need to change the list of repos that are 
assigned to a profile. Attempt to do it in WebUI fails. I select profile 
to edit. I have two repos assigned to it (Everything and updates). I 
want to have only Everything, but drop updates. So, I select only 
Everything (by clicking on it) The other one is de-selected (good - just 
what I want!). Then I save profile, but no changes are saved. If I look 
at this profile again - same 2 repos are highlighted. Changes made to 
other fields seems to work just fine.
I see that both on the cobbler version 2.0.2 installed from testing repo 
and on the git master.

I can make changes in profile with CLI.

I submitted Ticket #560.
