I would also like to request different feature types from one WFS server into on vector layer.
Today I use this behaviour to add one layer to my application and can afterwards decide, which typenames to request from the server. I haven't to add three separate layers. I do not use grouping in the mapfile, instead i change with mergeNewParams the typename parameter for the request. A simple example shows this: http://gis.ibbeck.de/ginfo/apps/OLExamples/OL26/examples/styles_unique_with_ group_wfs.html Arnd Wippermann -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Tim Schaub Gesendet: Donnerstag, 6.

Yeah, this is because up until this point, vector formats have been used to read/write collections of features, and I think of collections of features as layers. I'd like to continue thinking that way (because I think it works). But I know there are people who are interested in making WFS requests for multiple feature types (which I like to think of as layers). I really want to get WFS working for the most common cases. And I want it to be solid (with good support for transactions and filtered queries). I've made a boatload of changes in the topp/wfs sandbox - including changes to the GML & Filter code. My spare energy will be focussed on getting this code (the WFS protocol and related GML & Filter changes) in to the trunk. Modifying the existing GML code is a bit at odds with that. I also know that it will make sense to have the protocol be used in the absence of a layer. And of course we want to support our OGC protocol power user(s). Bart, can you describe (perhaps again) where you want to make a single request for multiple feature types. I'm sure it is done all the time, I just usually see a way that I think it simpler, so I'm curious to hear more use cases.
