Hi,
At least gml info format is returning also the geometries of the features found
with GetFeatureInfo as gml. Clients can utilise that for example by flashing
the queried feature.

Thanks for that I shall have a look at the sql from Oracle

Hi,
Best thing you can do is to catch the geometry which is returned by your query.
For me the error says that the returning feature collection is something that
FeatureCollectionDecorator cannot turn into a simple feature collection. I
would guess that for example feature collection containing both points and
polygons could make such trouble.
If your data are in PostGIS you can set PostgreSQL to log all the incoming SQL.
Perhaps by setting Geoserver logging level from the global settings into
GEOTOOLS_DEVELOPER_LOGGING you can collect that information into Geoserver log.
Once you can have captured the actual SQL resend it with PSQL command line and
see what comes back.

Hi
Sorry Thought I had included the geoserver version information at the bottom
of the original email
Gavin
*
Build Information
* Version 2.2-SNAPSHOT
* Subversion Revision 17075
* Build Date 14-May-2012 19:13
* GeoTools Version 8-SNAPSHOT (rev 38723
The full request is
unitPicker = new OpenLayers.Control.WMSGetFeatureInfo({
url: 'http://geology.data.vic.gov.au/services/mapping/ows',
layerUrls: ["http://geology.data.vic.gov.au/services/mapping/ows";],
title: 'Identify features by clicking',
queryVisible: true,
layers: [unitLayer],
} );
unitPicker.infoFormat = 'application/vnd.ogc.gml';
unitPicker.events.register("getfeatureinfo", this, pickUnitid);
If I use infoFormat = "text/plain" it all works
If I use any xml based format for infoFormat it errors
This works fine on another instance
Version 2.1.1
Subversion Revision 16080
Build Date 23-Jun-2011 10:45
GeoTools Version 2.7.2 (rev 37473)

Hi
When I do a WMSGetFeatureInfo request from open layers to geoserver using
unitPicker.infoFormat = 'application/vnd.ogc.gml';
Geoserver returns a <ServiceException>
java.lang.ClassCastException:
org.geoserver.wms.featureinfo.FeatureCollectionDecorator cannot be cast to

You should provide more information about your case. Just to get started:
* GeoServer version
* are you querying a app-schema layer?
* the GetFeatureInfo URL used (you should be able to grab it using firebug or
other web dev tools)
Cheers
