Nathan Wiese created GEOS-4937:
----------------------------------
Summary: Error "Operation on two geometries with different SRIDs"
appears for views with null geometries in first row
Key: GEOS-4937
URL: https://jira.codehaus.org/browse/GEOS-4937
Project: GeoServer
Issue Type: Bug
Components: PostGIS
Affects Versions: 2.1.3
Environment: Windows 7 (64 bit), PostgreSQL 9.0.4, PostGIS 1.5.3
Reporter: Nathan Wiese
Assignee: Andrea Aime
Hallo GeoServer Team,
I created the following data set in PostgreSQL/PostGIS:
-- feature data
CREATE TABLE city (id int, name varchar, population int, PRIMARY KEY(id));
INSERT INTO city VALUES (1, 'Aachen', 258664);
INSERT INTO city VALUES (2, 'Berlin', 3490445);
-- geometries for features in low resolution
CREATE TABLE city_geometry_low_res (id int, PRIMARY KEY(id));
SELECT AddGeometryColumn('city_geometry_low_res', 'the_geom', 4326, 'POINT',
2);
INSERT INTO city_geometry_low_res VALUES (2, GeomFromText('POINT(52 13)',
4326));
-- geometries for features in high resolution
CREATE TABLE city_geometry_high_res (id int, PRIMARY KEY(id));
SELECT AddGeometryColumn('city_geometry_high_res', 'the_geom', 4326, 'POINT',
2);
INSERT INTO city_geometry_high_res VALUES (1, GeomFromText('POINT(50.772341
6.102912)', 4326));
INSERT INTO city_geometry_high_res VALUES (2, GeomFromText('POINT(52.540558
13.406748)', 4326));
CREATE VIEW city_view AS SELECT * FROM city NATURAL LEFT OUTER JOIN
city_geometry_low_res city_geometry_low_res(id, the_geom) NATURAL LEFT OUTER
JOIN city_geometry_high_res city_geometry_high_res(id, the_geom2);
This gives me the following view:
id; name; population; the_geom, the_geom2
-----------------------------------------
1; "Aachen"; 258664; ""; "0101000020E6100000122EE411DC624940BC7669C361691840"
2; "Berlin"; 3490445; "0101000020E61000000000000000004A400000000000002A40";
"0101000020E6100000ABCB290131454A40446D1B4641D02A40"
After having published the view as layer in GeoServer, I get the following
error message in the layer preview:
"Internal error occurred java.io.IOException null FEHLER: Operation on two
geometries with different SRIDs"
In the log file, this error appears:
2012-01-26 16:49:32,202 DEBUG [org.geotools.jdbc] - SELECT
encode(ST_AsBinary(ST_Force_2D("the_geom")),'base64') as "the_geom" FROM

0)

java.lang.RuntimeException: java.io.IOException at
org.geotools.data.store.ContentFeatureCollection.features(ContentFeatureCollection.java:212)
...
The query "SELECT DISTINCT srid(the_geom) FROM city_view" results in two rows:
NULL and 4326.
I suspect it could have something to do with this:
"if no SRID can be found in the geometry columns just look into the first
geometry"
source: http://jira.codehaus.org/browse/GEOT-2664
Because when I switch rows, everything is fine.
Best wishes,
Nathan
