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

[Eduardo José Ramos]

Bart, thanks for your time.

The request doesn't go off at all... firebug console is empty. No javaScript errors or warnings... 

It adds the layer name to the layer control but nothing else happens.

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
