[mapguide-internals] ogr postgis layer problems

[Traian Stanev]

That was being caused by the FID filter not working, at least in the
case of SHP. Not sure if the Postgres driver does anything differently.
Can you try connecting to an SHP file (with the OGR provider) to see if
selection highlights in the case of SHP. That way I'll know at least the
code path I fixed is working for you.

Thanks Traian, that fixed the problems.  There is one small remaining
issue that is not critical - the selected features (postgis again) don't
seem to highlight in the ajax viewer.

Cheers
