[rt-users] What determines whether ticket resolution responds to requestors or not?

[Vicki Stanfield]

I have been asked to change the Update Type to "Respond to Requestors" 
when resolving tickets. I have seen code to do this, but my question is 
more basic. It seems that sometimes when I resolve tickets, it is set to 
"Respond to Requestors" and other times not. Can someone explain the 
criteria that determine which update type is used?
