[mapserver-dev] strange problem with WFS and ArcSDE layers

[bartvde at osgis.nl]

Okay, after some debugging I found this is caused by mapwfs.c, the
following line:

bbox = map->extent = ext;

it changes the map extent to the layer's extent, but since the queries are
run in another loop, this is a global setting and the map extent will have
the extent of the last query layer.

This changeset introduced this:
http://trac.osgeo.org/mapserver/changeset/7674

Tom, are you able to comment on this?

Best regards,
Bart
