[rt-users] Re-Display Ticket with added warning if owner changed during responding

[David Schmidt]

Hello

In case someone takes the ticket ownership wile I am composing a 
response I would like to redisplay the ticket (the submitted response 
shouldnt be deleted) and add a warning informing the user about the 
change in ownership.

I guess this is the correct callback

html/Callbacks/RT-Extension-WarnTicketTaken/Ticket/Update.html/BeforeSubmit

but /Ticket/Update.html is quite the monster for an unexperienced RT 
dev. :)

Where can I get the response text from so it doesnt get lost and how do 
I add a warning?

regards
david
