[Mapbender-users] problems with digitize GUI with geoserver as WFS-T

Hi mapbender-users, hi Arnulf and Cristoph,

I was able to narrow the problem a little bit down:
First of all I'm using our own WFS-T based on geoserver (may be that's 
the reason why there's on of the ccgis-Server called for the 
xsi:schemaLocation - what ever this is).
the WFS-T works together with mapbender without problems (editing, 
moving, creating, and deleting of pointProperties. The error only occurs 
with MultiPolygon / Polygon. In the geoserver.log (wich produces about 
4000 lines if loging "FEINER" just for one polygon-transaction I get the 
error message (if this is the relevant error):

23.03.2007 15:07:05 org.vfny.geoserver.servlets.AbstractService sendError
SCHWERWIEGEND: Service exception occurred
org.vfny.geoserver.wfs.WfsException: java.lang.RuntimeException: problem 
creating feature
Caused by: IllegalAttribute: com.vividsolutions.jts.geom.Polygon , but 
got com.vividsolutions.jts.geom.MultiPolygon
Caused by: java.lang.IllegalArgumentException: 
com.vividsolutions.jts.geom.MultiPolygon is not an acceptable class for 
the_geom as it is not assignable from class 
Does this ring a bell?
The postgis polygon is of type MULTIPOLYGON in the "geometry_columns" - 
in geoserver the type is also multiPolygonProperty and mapbender handles 
the data also as "MultiPolygonPropertyType".

Seems to be a similar problem like (?):

But my describefeaturetype works with this URL:

Well, to be honest - I think there's still a lot for me to learn in this
