Can you send me a larger code example illustrating how you create the filter and select command?

Subject: [fdo-users] WFS FDO Spatial Filtering

Hi I've been trying to get the FDO WFS provider (3.4) to just send me the
features within a geometric envelope.
I tried adding a spatial filter (as a string) to the Select Command but I
get an exception "parameter Geom not recognised" from the WFS provider and
it works fine in the FDO OGR provider.

Does the WFS provider support spatial filters or not - I'm a little confused
- the Provider itself
includes FdoConditionType_Spatial in the supported FilterCapabilities along
with lots of geometry operations in the supported SpatialOperations, yet the
developer guide says no filtering is supported by WFS at all.

So which is correct, the guide, or the returned list of filter capabilities?
If the WFS provider really does support spatial filtering then what am I
doing wrong?
and if not is there another means (within the context of being an FDO
feature consumer) to restrict the features returned to a small envelope.

here is one of my filter strings for reference:
"Geom INTERSECTS GeomFromText('POLYGON ((495566.0 324296.5, 577840.0
324296.5, 577840.0 230844.25, 495566.0 230844.25, 495566.0 324296.5))')"
