Hi Stefan, I am afraid I do not understand :-( Do you think this is a bug in OJ? The multipolygon causes an error the geometrycollection not.
Is this behaviour OGC-conform (simpel features...)? What do you think? uwe Am 08.04.2013 16:36, schrieb Stefan Steiniger: > Hi, > > so - well the situation is not so nice, as it should be valid.
