Hi Andrea,
Thanks! The issue seems solved with your patch. For the record the, or
another issue appeared in a different form in 2.1-beta3 (see below) but
seems fixed as well. This all is on Ubuntu 9.10 32b (I never do Windows).
I checked first with unpatched 2.1-beta3 and saw 2 types of issues with
those shapefiles:
1) 21 Dec 11:37:22 ERROR [geoserver.ows] -
org.geoserver.platform.ServiceException: The requested Style can not be
used with this layer. The style specifies an attribute of STRNAAMNL and
the layer is: inspire:gn_wegdeel_punt
at
org.geoserver.wms.map.GetMapKvpRequestReader.checkStyle(GetMapKvpRequestReader.java:1051)
2) 21 Dec 11:54:58 ERROR [geotools.rendering] - PropertyDescriptor is
null - did you request a property that does not exist?
org.geotools.data.DataSourceException: PropertyDescriptor is null - did
you request a property that does not exist?

I was sure that these attributes as refered in the SLD exist. When going
to the layer edit page, there was only the geometry attribute of the
layer. When clicking "Reload feature type", all other attributes
appeared and the above errors were gone. However the errors reappeared
after each GS restart.
After substituting your gt-shapefile-2.7-SNAPSHOT.jar for the one in
2.1-beta3 the issues never occurred again. The more strange since both
versions of gt-shapefile-2.7-SNAPSHOT.jar were equal in size and just
differed in one byte:
cmp gt-shapefile-2.7-SNAPSHOT.jar
../../gt-shapefile-2.7-SNAPSHOT.jar.old differ: byte 11, line 2 . But
ok, one byte can make all the difference !
best,
