firewall config vs apache config

i am performing an autoinstall of sles 10 with a control file. it seems that firewall config in http-server conflicts with firewall settings that instruct to open access for http service. if <firewall> section has http as an allowed service, but <http-server> has <firewall config:type="boolean"> set to false (or missing), port 80 is not opened. is this the intended behaviour or have i missed something ? -- Rich
