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

[Bart van den Eijnden (OSGIS)]

Without seeing your actual WFS it is hard to help.

But here it goes:

1) featureType should be MonkeyIsland
2) check if your featureNS does not end with / in the XML returned by your
WFS, this would also break the parser. So maybe
http://www.mapinfo.com/wfs/ instead of http://www.mapinfo.com/wfs

Best regards,
Bart
