[OpenLayers-Users] Re: Problems getting WFS layer

[Casper Span]

Hi Bart, Mark,

There is nothing related to WFS on the console, nor on NET's XHR subtab.
Even when everything is checked. It's like it crashes before it gets
there... (with no error, ofcourse...) I've also tried your suggestion, Mark.
Still the same.

The DescribeFeatureType:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:gml="
http://www.opengis.net/gml" xmlns:gs="http://casp-geoserver/"
elementFormDefault="qualified" targetNamespace="http://casp-geoserver/">
  <xsd:import namespace="http://www.opengis.net/gml" schemaLocation="
http://localhost:80/geoserver/schemas/gml/3.1.1/base/gml.xsd"/>
  <xsd:complexType name="locatiedossiersType">
    <xsd:complexContent>
      <xsd:extension base="gml:AbstractFeatureType">
        <xsd:sequence>
          <xsd:element maxOccurs="1" minOccurs="0" name="ID" nillable="true"
type="xsd:decimal"/>
          <xsd:element maxOccurs="1" minOccurs="0" name="GEOMETRY"
nillable="true" type="gml:GeometryPropertyType"/>
        </xsd:sequence>
      </xsd:extension>
    </xsd:complexContent>
  </xsd:complexType>
  <xsd:element name="locatiedossiers" substitutionGroup="gml:_Feature"
type="gs:locatiedossiersType"/>
</xsd:schema>


Hmm... I just tried another request from a different pc... now I suddenly
DID get some xhhtp on the NET panel:

So basically, it can't find anything... Maybe this is a projection related
issue then... The data is EPSG:28992,

My Map options hash have:
projection: new OpenLayers.Projection("EPSG:4326"),
displayProjection: new OpenLayers.Projection("EPSG:28992"),

Could there be a mixup there? I still find the projection/displayProjection
really confusing... what's the real difference between the two?

regards,
Casper
