Correct, the only support for this is running the filter in memory, which is when the PropertyExtractor comes in. The reason it cant be encoded is because the encoder tries to run the PropertyName extpression @gml:id against the type first. The reason it does this is because the expression might not equal the attribute type name. So things like gml:name get mapped to name, etc... However with @gml:id... there is no attribute type, so the encoder bows out. I guess it could consult the fid mapper in some way... but there is no good way for a property extractor to know about it. > > Glub... confused... anyone has a better understading of what's going > on with this @gml:id thing? > > Cheers > Andrea > > ------------------------------------------------------------------------- > This SF.net email is sponsored by the 2008 JavaOne(SM) Conference > Don't miss this year's exciting event.
