Question regarding Outputfilter in OTRS 4.0

Hey guys,

is there any reason or trick to prevent an Pre or Post Outputfilter is
started 3 times in AgentTicketZoom?

I created a small Outputfilter for the AgentTicketZoom and it gets started
3 times, always with the same template. The other templates are fine. Any
ideas on that?


OTRS Version is 4.0.5.

Thanks in advance.

Johannes
