[mapserver-users] classgroup and group

[Steve.Toutant at inspq.qc.ca]

Hi,
I can't figure out how classgroup and group work. I have defined the 
following layer. Using it with this query
http://ipaddress/cgi-bin/mapserv.exe?map=\path\mapfile.map&mode=map
I get all the points on a map but the style is not applied. 
If I remove the 2 CLASSGROUP statements but keep the GROUP key and launch 
the same query the layer features show up with style applied.
why is that?

Also, Is it possible to define a query string and specify which classgroup 
to show on the map? What would be the parameter then? I tried &group= xxx 
and &classgroup=xxx and it didn't work
thanks
Steve
