[otrs] possible small bug when owner change ? (page refresh)

The context is "My Colleague is gone to holidays, so I want to get some of his tickets". All I have to do is select his ticket (For example thru the StatusView module), and change the owner from there. I works well except the ticket view after validating the owner-change form doesn't show any email or phone answers links. To view it, you have to get out of this page for example by returning to the queue view then get back in the ticket details ... Is it expected ? -- Martin
