Re: [Gwt-openlayers-devl] WFSprotocol and Vector Layer

[Edwin C. <com...@gm...>]

Hi Poul,

I checked and it seems it are not the options where it goes wrong in
the BasicWFS example. When I post the WFS query generated by the
wfsExample layer with Poster (a Firefox add-on) then I get back a WFS
FeatureCollection, but when the WFS query goes through the
gwtOpenLayersProxy I get an error message:

<ows:Exception exceptionCode="MissingParameterValue" locator="request">
<ows:ExceptionText>Could not determine geoserver request from http
request POST /geoserver/wfs HTTP/1.1 (...) </ows:ExceptionText>

Sth seems go wrong with proxying the request.

Do you use the gwtOpenLayersProxy, the OL Python proxy, or some other proxy?

Are all the options you specify necessary? It seems that you are
passing the default geometryName and srsName, only a non-default WFS
version. The schema location is optional and in the OL example the
schema location is not used. Maybe only specifying the non-default WFS
version is enough for you.

Greetings,
Edwin
