[Zoo-discuss] valid GML string

[Steve.Toutant at inspq.qc.ca]

I'm still unable to use the services provided in zoo trunk.
Someone on this list succesfully send a GML to the centroidPy?

I'm trying to use CentroidPy with a GML as input. Sorry for the long 
post...below is the config and request

I always get the error
[error] ERROR 1: GML Geometry is empty in OGR_G_CreateFromGML()., referer: 
http://10.2.198.132/geo/igo/wps/client/ol/

Here is the GML v3. It is valid since I use it in other applications
<gml:featureMember xmlns:gml="http://www.opengis.net/gml" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://www.opengis.net/gml 
http://schemas.opengis.net/gml/3.1.1/profiles/gmlsfProfile/1.0.0/gmlsf.xsd"><feature:feature 
xmlns:feature="http://example.com/feature"><feature:geometry><gml:Polygon><gml:exterior><gml:LinearRing><gml:posList>-78.8818359375 
40.374755859375 -76.0693359375 60.062255859375 -57.0849609375 
48.109130859375 -78.8818359375 
40.374755859375</gml:posList></gml:LinearRing></gml:exterior></gml:Polygon></feature:geometry></feature:feature></gml:featureMember>

I have tried with a GMML fragment for the geometry also, I get the same 
error
<gml:Polygon><gml:exterior><gml:LinearRing><gml:posList>-78.8818359375 
40.374755859375 -76.0693359375 60.062255859375 -57.0849609375

40.374755859375</gml:posList></gml:LinearRing></gml:exterior></gml:Polygon>

Here is the config CentroidPY
[CentroidPy]

 processVersion = 1
 storeSupported = true
 statusSupported = true

 <DataInputs>
  [InputPolygon]
   Title = Polygon to get the centroid
   Abstract = The centroid which is not necessarily within the geometry.
