I'm using Geoserver 2.5.1 with PostGIS 2.1.3 and the ImageMosaic plugin. I
have successfully been able to use CQL_FILTER to query a my ImageMosaic layer
by time and by my own custom attribute, now I am trying to create a spatial
query using something like:
CQL_FILTER=BBOX(the_geom, 48.46, 19.04, 49.4, 19.07)
and the full WMS GetMap request looks like:
wms?service=WMS&version=1.1.0&request=GetMap&layers=GeoCenter:gc_mosaic_hd&styles=&bbox=48.4598350524902,19.0338842710851,49.44959107524,19.0846311684303&width=6436&height=330&srs=EPSG:4326&format=application/openlayers&CQL_FILTER=BBOX(the_geom,
48.46, 19.04, 49.4, 19.07)
The raster column created by the ImageMosaic plugin is called "the_geom" and is
of type "geometry(Polygon, 4326)". When I use the GeoServer Layer Preview with
OpenLayers and add something like "&CQL_FILTER=BBOX(the_geom, 48, 18, 49, 19)"
to the WMS GetMap URL I get no images and the GeoServer log has the below
stacktace:

According to the GeoServer tutorial
http://docs.geoserver.org/stable/en/user/tutorials/cql/cql_tutorial.html the
BBOX syntax I am using is valid. I also have a separate vector layer
containing the footprints of the granules in the ImageMosaic and the same
CQL_FILTER works for that layer.
Can anybody tell me why I would be getting this error? Do spatial queries with
CQL_FILTER parameter not apply to an ImageMosaic raster layer?
