[mapguide-internals] ogr postgis layer problems

[Traian Stanev]

Hi again.

I've fixed both issues in the OGR provider. Selection now works fine,
including multi-select, when tested on SHP files. There was a problem
with intersection queries (the problem was they weren't implemented,
heh). I also fixes the problem of the features disappearing after
selection -- I had forgotten to reset the filters on the OGRLayer in
between Selects. I also fixed a small problem in OGR, which was making
FID filters fail. I'll have Tom post a new Win32 DLL to the provider
download location. 

FYI, I recompiled against the following versions of the dependent
libraries: GDAL 1.4.0 (plus my fix), PostgreSQL 8.2.1, Proj 4.5.0, Geos
2.2.3, plus unknown versions of Oracle OCI and ODBC.

Hi Paul. 

I tried it against an SHP file and selection is definitely not working
right. :) To avoid the disappearing map problem, you can disable
connection pooling for the OGR provider in the serverconfig.ini file.
This will prevent the map from disappearing (since the connection is not
reused after it breaks during selection), but it will not make selection
work. I will see what can be done about fixing this and let you know.

Hi all,

I am looking into an issue regarding postgis layers loaded via the OGR
provider for a client.  The postgis layer is functioning normally when
the map loads (it is initially off but it can be toggled on/off no
problem).  It can be queried using the select.  However, when the layer
has had features selected on it, the next action causes the layer to be
turned off and the layer cannot be turned back on without restarting the
service and web browser.

Any ideas what might be going on?  Bug in the OGR provider?  AJAX
Viewer?  Bad data?

Cheers

Paul
