[Users] How to feed a Grid from several WFS Layers

[Andreas Hocevar]

Hi,

if your WFS supports multiple feature types per request, you should also be able to configure your OpenLayers vector layer with a comma separated list of feature types. The requirement, of course, is that all WFS layers are on the same server and have the same namespace.

Regards,
Andreas.
