[Mapserver-users] unable to affect HTML legend via URL arguments to map file elements

[Emilio Mayorga]

I'm trying to impact the output of an HTML legend by using URL CGI 
arguments. For example, if in my map file there is a layer with these 
elements:
NAME  "countries"
GROUP "political"
I want to change the group to "admin" on the fly using this URL CGI snippet:
&mode=legend&map_countries_group=admin

However, the HTML legend seems to be completely unresponsive to changes 
passed via the map_<layer name>_<layer subelement> syntax (I've tried 
various changes). Is that so, or am I doing something wrong?

Thanks for your help! Cheers,
