[OpenLayers-Users] Informations by onmouseover / alternative to WFS?

[Kai Behncke]

Hi Bart,

thank you for that hint.

I have got it to run with the wms/wfs of  

layer = new OpenLayers.Layer.WMS(
"States WMS/WFS",
"http://demo.opengeo.org/geoserver/ows",
{layers: 'topp:states', format: 'image/gif'}
            );

but I had no luck so far with my own wms/wfs.

I use MapServer 5.4 and I have build also ONE mapfile that works as WMS AND WFS.

If I do a mouseover on the areas I can see in firebug that the wfs is recognised, I get back e.g.

.....but the hovering/highlighting does not work.

Has anybody an idea why this can be?
Do I need any special entries in the Mapfile?

The typical WMS/WFS-requests work fine so far.

Thank you very much, Kai
