WFS_getFeature-1.1.xml throws NullPointer exception
----------------------------------------------------
Key: GEOS-2211
URL: http://jira.codehaus.org/browse/GEOS-2211
Project: GeoServer
Issue Type: Bug
Components: PostGIS, WFS
Affects Versions: 1.6.4
Environment: Mac OS X running in tomcat 6.0.18 using Java 1.5.0_13 against postgis-1.3.3 on postgresql 8.3.1
Reporter: Nick Palmer
Assignee: Andrea Aime
When doing a WFS_getFeature-1.1 request I get a NullPointerException
Steps to Reproduce:
Install geoserver.war from 1.6.4 release into tomcat and deploy.
Add a new namespace.
Add a new postgis datastore in that namespace.
Create a view with an oid and geometry column with a POINT in the geometry column. I have a single row in that view.
Create a new feature set against the view.
Go to Demo and select Demo Request: i.e. /geoserver/demoRequest.do
Select WFS_getFeature-1.1.xml
Delete the filter from the query and change the feature set to be the one you just created.
That is, the request is:
<wfs:GetFeature service="WFS" version="1.1.0"
xmlns:topp="http://www.openplans.org/topp"
xmlns:wfs="http://www.opengis.net/wfs"
xmlns:ogc="http://www.opengis.net/ogc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.1.0/wfs.xsd">
<wfs:Query typeName="namespace:feature">
</wfs:Query>
</wfs:GetFeature>
This results in the following in the logs:
10 Sep 18:01:33 DEBUG [org.geotools.data.jdbc] - About to execute query: SELECT "oid", encode(asBinary(force_2d("geom"),'XDR'),'base64') FROM "public"."feature" LIMIT 1000000
