[OpenLayers-Users] wfs not displaying

[Sarah Schuessler]

Hi,

thanks for your suggestion!
Name of the layer is correct. I use featureType: "mylayer" (without prefix) and/or typename: "gn:mylayer" but neither worked.
Firebug gave me:
 gml:boundedby ><gml:null>unknown</gml:null>
I think because of different EPSG/coordinates. But don´t know how to manage best way.

best regards
Sarah

Hello,

What is the name of your layer in the Server? You don't seem to be passing that to the layer constructor. Do 2 things:

. confirm in the server the layer's name and that there's nothing wrong with it (accessing the demos at Geoserver);

. try a simpler layer setup like the following in a map with the same SRS:

var wfs2 = new OpenLayers.Layer.WFS( 
                "myLayer",  
                "http://myserver:81/geoserver/wfs", 
                { 
                 typename: 'myLayersNameInTheServer', 
                } 
            );

If it shows as expected you can try to build it up from there.

Good luck,

Luís
