[mapserver-users] WFS Getfeature returning incorrect features

[Fong,Phil [Burlington]]

Hello,

I have a mapserver (5.2.1) setup that is returning incorrect features
from a WFS getfeature request. For example, if a bbox is specified:
bbox=-100,50,-99,51, then some point features outside of bbox get
returned. However, the overall bounding box of the features (in the
gml:boundedBy element) looks right and is inside the bbox, but is not
representative of the features that are returned (see below). Also, if I
try different bboxes, it would appear that it's always  taking the first
N (which varies) features in the layer (sites.1, sites.2 always appear).


What is going on and how to fix? Has anyone else encountered this odd
behaviour? The point features are stored in a database table (mssql to
be specific) and connection is using OGR (through ODBC). Mapserver is
running in Windows Server 2003 (64-bit).

Thanks for any help.

-Phil
