[OpenLayers-Users] Re: Problems getting WFS layer

[Bart van den Eijnden]

Hi Casper,

AJAX requests normally show up in the Console tab of Firebug, make you sure you have activated the option to show AJAX requests.

Without a request XML and response XML it's really difficult to help you.

Otherwise, send us the output of your DescribeFeatureType request, a common mistake is that the featureNS does not exactly match the namespace advertized on the WFS.

Best regards,
Bart

Firebug tries to get something from WFS "OPTIONS wfs", but the reponse is empty. That's the only WFS related line on the NET tab in FireBug.
