Hi again, well I think i got the Problem.
Everytime I switch between Eclipse an Firefox the "onfocus" - Event is triggered. Am I right? So that's the reason why the "MyAjaxEventBehavior called" will be displayed that often? Wouldn't that be a problem in a productiv environment? For example: A user starts his application within a browser an activates an "onfocus" field. Whyever he has to change from his webbrowser to another app and when he returns the "onfocus" - Event is triggered again. Is this a normal "onfocus" behavior?
