[Mapserver-users] WMS and Querymap: Show several layers in querymap

[Till Adams]

Dear Daniel,

and to all who don't need more growing grey hair...

thanks - your workaround did it!
We added hard-wired layer names to the query_layers list and the 
(hard-wired) layers are drawn in the query-map.
If one of the hard-wired layer does not exist in the mapfile, the 
querymap with the other layers is drawn anyway, without any error mesage 
-- that's comfortable.

Greetings,
Till ;-)
