[Bug 10720] No "Available Columns" 

http://bugs.otrs.org/show_bug.cgi?id=10720

Hi Martin,

I have fixed this in Dashboard screen. As I have  mentioned before, there is not a problem in AgentTicketSearch and the others screens with "Settings filter options". There was a problem only for Dashboard filter settings.  
There is a little different logic for update those preferences, because it works with AJAX, and I found  some solution, please follow-up this.
If I can improve it, let me know.

Regards
Zoran
