Error: Save Firewall Rule

Hello

i have a problem when i save my new rule, ASG220 will give me back this error message:

The firewall rule list needs Paketfilter objects.

The syslog say´s:

2012:07:18-11:18:30 gwro confd[2690]: W Message::err_set:973() => id="3100" severity="warn" sys="System" sub="confd" name="NODE_OBJECT_BADREF (The firewall rule list needs Paketfilter objects.)" user="admin" srcip="10.10.11.150" facility="webadmin" client="index.plx" call="set" goodclass="packetfilter" nodelist="packetfilter->rules" check="input" badref="REF_PacPacAnyFromHostt2"

What can i do to resolve this problem?

Thank you

Jens
