[OpenLayers-Users] Can WFS protocol change between two calls ?

[Flavien.Audin]

Hi everybody,

Here my situation : I set up a map with one WMS layer (geoserver) and I want
to select the feature with the OpenLayers.Control.GetFeature(...) using a
WFS protocol.

It's working well if I ask for one featureType
(featureType:"guadeloupe_ways" in the WFS protocol options). I select
features with a box and a function add them to a OL.Vector.Layer() (event
"featureselected"). Ok

But If I ask for two featureTypes :
featureType:["guadeloupe_ways","guadeloupe_vertices"] in the WFS protocol
options, it's working only for the first call (I mean the selection works as
with one featureType), but for the second call (If I try to select other
features), it can't find the featuretype.
I looked in the POST request with the firebug console and I find this :

First call :
<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" service="WFS"
version="1.1.0" xsi:schemaLocation="http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.1.0/wfs.xsd">
  <wfs:Query typeName="DEVPgRouting:guadeloupe_ways" srsName="EPSG:900913">
    <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc">
      <ogc:BBOX>
        <gml:Envelope xmlns:gml="http://www.opengis.net/gml"
srsName="EPSG:900913">
          <gml:lowerCorner>-6850334.7079709
1827921.1127902</gml:lowerCorner>
          <gml:upperCorner>-6845557.3937038
1832010.4938028</gml:upperCorner>
        </gml:Envelope>
      </ogc:BBOX>
    </ogc:Filter>
  </wfs:Query>
  <wfs:Query typeName="DEVPgRouting:guadeloupe_vertices"
srsName="EPSG:900913">
    <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc">
      <ogc:BBOX
        <gml:Envelope xmlns:gml="http://www.opengis.net/gml"
srsName="EPSG:900913">
          <gml:lowerCorner>-6850334.7079709
1827921.1127902</gml:lowerCorner>
          <gml:upperCorner>-6845557.3937038
1832010.4938028</gml:upperCorner>
        </gml:Envelope>
      </ogc:BBOX>
    </ogc:Filter>
  </wfs:Query>
</wfs:GetFeature>

and the response contains all the features : good.

For the 2nde call :
<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" service="WFS"
version="1.1.0" xsi:schemaLocation="http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.1.0/wfs.xsd"
  <wfs:Query xmlns:DEVPgRouting="devpgrouting"
typeName="DEVPgRouting:guadeloupe_ways,guadeloupe_vertices"
srsName="EPSG:900913">
    <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc">
      <ogc:BBOX>
        <ogc:PropertyName>the_geom</ogc:PropertyName>
        <gml:Envelope xmlns:gml="http://www.opengis.net/gml"
srsName="EPSG:900913">
          <gml:lowerCorner>-6844601.9308504
1826850.9943943</gml:lowerCorner>
          <gml:upperCorner>-6840168.5832104
1830634.6272939</gml:upperCorner>
        </gml:Envelope>
      </ogc:BBOX>
    </ogc:Filter>
  </wfs:Query>
</wfs:GetFeature>

And the response is the following exception : 
<?xml version="1.0" encoding="UTF-8"?>
<ows:ExceptionReport version="1.0.0"
  xsi:schemaLocation="http://www.opengis.net/ows
http://***url***:8082/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ows="http://www.opengis.net/ows">
  <ows:Exception exceptionCode="InvalidParameterValue" locator="typeName">
    <ows:ExceptionText>Could not locate
{devpgrouting}guadeloupe_ways,guadeloupe_vertices in
catalog.</ows:ExceptionText>
  </ows:Exception>
</ows:ExceptionReport>
=>not good :(

I understand the problem for geoserver to find the good layers, but I don't
understand why the WFS protocol send only one element <wfs:query ...>
instead of two as for the first call.

If anyone is able to explain why, I'll be glad to hear it :) Maybe I've done
something wrong...
