Andrea,
Thanks a lot for your reply,
I've tried this, it works fine when styling a table not a view. When styling a
table the function SimpleFeature.getID() returns the record id as
"layer-name.123", so I can extract the integer id "123" from it, but when
styling a view, this function returns something like
"fid-465fb2a-d12faf_-5f42a", so no integer id is contained.
Regards,
Fawzy
