Hi Justin, I am having a very similar problem with views in PostGIS after upgrading to 2.0 2009-10-30 16:11:21,237 WARN [geotools.jdbc] - No primary key or unique index found for tod_projects_residential. 2009-10-30 16:11:21,252 INFO [geoserver.catalog] - Loaded feature type 'DRCOG:tod_projects_residential' The layer loads but is blank in the openlayers preview. To confirm, there is no entry of the views in the geometry_columns table. Would a solution be to just add the views to the geometry_columns table?

Subject: Re: [Geoserver-users] 1st post - Help - Geoserver 20a on tomcat6 Hi Franco, What we meant was that GeoServer 2.0 requires any views to have the geometry column registered in the geometry_columns table, whereas 1.7.x did not. This is a bug that has been reported in the tracker. http://jira.codehaus.org/browse/GEOT-2664 Can you confirm that your views have or don't have geometry column entries? -Justin Franco Nogarin wrote: > So, if I understand, you are saying that the reason all of my geoserver > 1.7.x data in postgis, which is all in views, is not working in 2.0 is > the heuristic approach has been removed. > If so, what then do I need to do to make my views geoserver 2.0 compatible. > here is a view that works perfectly under 1.7.4 but not at all under 2.0 > -- View: v_stations > > -- DROP VIEW v_stations; > > CREATE OR REPLACE VIEW v_stations AS > SELECT n.nid AS oid, n.nid, n.title, > st_x(ctw.field_stn_location_openlayers_wkt::geometry) AS x, > st_y(ctw.field_stn_location_openlayers_wkt::geometry) AS y, > ctw.field_elevation_value AS elevation, ctw.field_stn_type_value AS > type, geomfromtext(ctw.field_stn_location_openlayers_wkt, 4326) AS geom > FROM node n > JOIN content_type_wxstation ctw ON n.nid = ctw.nid::integer > WHERE n.status <> 0 AND n.type::text = 'wxstation'::text; > > ALTER TABLE v_stations OWNER TO postgres; > > > On Thu, Oct 29, 2009 at 7:43 PM, Andrea Aime <aa...@op... > <mailto:aa...@op...>> wrote: > > Franco Nogarin ha scritto: > > Well, as I said, ALL of my postgis layers dont work. node_vid is > always an integer.
