[Chameleon] ExpressionBuilder problems

[bartvde at xs4all.nl]

Hi Roberto,

you can use the ExpressionBuilder on a WMS layer (CONNECTIONTYPE WMS).
Check the following document:

http://mapserver.gis.umn.edu/doc/wms-server-howto.html

AFAIK this will require Mapserver CGI, or any other WMS like Geoserver.

So in your Chameleon MAP file you use a WMS client layer, which refers to
the Mapserver CGI which connects to PostGIS.

If you just use a WMS client layer (and not a WFS client layer), no GML
will be sent over for the ExpressionBuilder.

Best regards,
Bart
