Thanks Ben, That makes a lot of sense. I was starting to think that something like that was the case.

McIntosh Cc: [email protected] Subject: Re: [Geotools-gt2-users] GeoTools and A feature name attribute The implementation of simple features in GeoTools is crippled by not being fully namespace aware. It assumes that all properties of a simple feature are in the same namespace as the feature type, and in some places it just doesn't care about namespaces at all. You can see this in, for example, SimpleFeatureImpl (one a many examples): public Property getProperty(Name name) { return getProperty( name.getLocalPart() ); } I suspect that this might be causing your problem. As a consequence of this defect, the "name" of your feature type collides with the (gml:) "name" of gml:AbstractFeatureType. Kind regards, Ben. On 13/08/10 13:36, Dale F.
