At this point I've no answer to these questions. Sorry. One other thing I've noticed: the two compared objects have different values for the _geom property (see above); however they have the same value for the __geom (_PointAdapter__geom really). Is this mismatch expected? -- Eric _______________________________________________ Community mailing list [email protected] http://lists.gispython.org/mailman/listinfo/community
