If you just want to stop AjaxSelfUpdatingTimerBehavior after a
particular event(or one call even), you could always call the stop
method on the AjaxSelfUpdatingTimerBehavior. No idea if this is the best
practice but it's worked for me.

Hi, guys,
I code AjaxSelfUpdatingTimerBehavior with isTemporary() {return true;}.
After being called once I get
