WFS sends unsupported functions to server
-----------------------------------------

         Key: UDIG-869
         URL: http://jira.codehaus.org/browse/UDIG-869
     Project: uDIG
        Type: Bug

  Components: wfs  
    Versions: UDIG 1.1.RC1    
    Reporter: Jesse Eichar
 Assigned to: Jesse Eichar 
    Priority: Blocker
     Fix For: UDIG 1.1.RC2



The Ionic WFS advertizes its geometry as a gml:GeometryAssociationType

<xsd:element name="ORA_GEOMETRY" minOccurs="0" nillable="true"
type="gml:GeometryAssociationType">

uDIG is trying to do a request using a function called geometryType which
is not supported by Ionic, so here the communication stops. The actual
request which is sent is:

/ionicweb/wfs/ORATEST?SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&FILTER=
<Filter xmlns="http://www.opengis.net/ogc"
xmlns:gml="http://www.opengis.net/gml"><And><BBOX><PropertyName>ORA_GEOMETRY</PropertyName>

</Filter>

My questions/remarks are:
1) why does uDIG add this filter? Does it need to make sure that only
geometry types are coming in that it can deal with?
2) shouldn't it check the WFS GetCapabilities response to see if this
function is supported? Also, in which OGC spec is this function defined?
3) if the function is not supported, should it not just do a normal
GetFeature request without this geometryType filter and just see what
geometry types arrive?
