Hi,
We are having problems with spatial filtering in in SLD used for WMS requests. The request below using the SLD that follows displays point features fine without the filter. The BBOX used in the spatial filter is the same as in the request for testing purposes but for some reason it seems like the spatial filter does not return any features.
Note that we use postgis and data using reference system EPSG:2400. Geoserver version is 1.6.2

We have tried to understand why by looking at geoserver logs also… which seem to indicate that the spatial operation isn’t correctly translated. The snippet below shows this:
2008-04-25 10:26:57,136 DEBUG [data.jdbc] - calling sql builder with filter [[ geom bbox POLYGON ((1380829.4 6191320.4, 1380829.4 6192971.6, 1382480.6 6192971.6, 1382480.6 6191320.4, 1380829.4 6191320.4)) ] AND [ geom bbox POLYGON ((0 0, 0 0, 0 0, 0 0, 0 0)) ]]
The bbox that is zeroed is what we think is wrong, but we don’t understand why this is included in the postgis request.

I believe this was fixed after 1.6.2, so try 1.6.3.
See:
