I have a very tricky problem: I have a Postgis 2.0 database, used as datastore for Geoserver 2.1.3
I have a table with a geometry column (named shape), with SRID 4326
I have created a view like this:
CREATE VIEW pippo AS SELECT st_geometryn(shape,1) as geom FROM events
And then I published the view using geoserver. Everything works, except for GetFeatureInfo requests, that fails with the error 'Operation on mixed SRID geometries A simple
select * from geometry_columns
returns that the SRID of pippo.geom is 0 (but should be 4326)
I tried also with this definition for the view
CREATE VIEW pippo AS SELECT st_setsrid(st_geometryn(shape,1), 4326) as geom FROM events
but I still have SRID=0 in the geometry_columns....any help?
Here is how the layer is defined in Geoserver:
I found a workaround to fix not the problem itself, but to let Geoserver to perform spatial search on GetFeatureInfo requests:
instead of creating a view and publish it, I published an SQL-layer defined directly in geoserver. In the layer-definition form it allowed me to select the right gemoetry type and SRID and everything is working now!
