(bug?) Snort Advanced configuration pass through doesn't work

[ronenb75]

Snort running on 1.2-BETA-1.

I've put "config disable_decode_alerts" the "Advenced" tab, the text box "Advanced configuration pass through".

If I'm looking at the /cf/conf/config.xml, I can see the config in there:

                <snortadvanced><config><bpfbufsize><bpfmaxbufsize><bpfmaxinsns><configpassthru>config disable_decode_alerts</configpassthru></bpfmaxinsns></bpfmaxbufsize></bpfbufsize></config></snortadvanced> 

But if I'm looking at /usr/local/etc/snort/snort.conf, I see just that:

# Snort user pass through configuration

#Rulesets, all optional

Which means that there is no configuration passing through to the snort.conf file. even after reboot, it's still empty, though it's still in the "Advanced tab and in the config.xml file.

Any ideas?
Is this a bug or I'm doing anything wrong?

Thanx.
