[OpenLayers-Users] Working with Openlayers.Layer.Vector and WFS

[Bart van den Eijnden (OSGIS)]

Eduardo,

featureNS should be http://www.mapinfo.com/wfs in your case.

What do you see using Firebug? Does the request go off at all? Does the
WFS respond with a proper FeatureCollection? Can you share a snippet of
the response?

Best regards,
Bart
