Hi list!
I'm trying to use a simple cross-layer filter in a WMS GetMap request, like
in a tutorial here:
http://docs.geoserver.org/stable/en/user/extensions/querylayer/index.html
Since I'm using GS2.1.1, I've copied querylayer-2.1.1.jar to a lib folder,
and restarted GS.
Then I've got lines
<ogc:FunctionName nArgs="-1">queryCollection</ogc:FunctionName>
<ogc:FunctionName nArgs="-1">querySingle</ogc:FunctionName>
in a WFS capabilities doc. Cool.
When I make a request (from an OpenLayers layer preview page):
http://myserv:8080/geoserver/eko/wms?LAYERS=eko:roads&STYLES=line&FORMAT=image/png&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&EXCEPTIONS=application/vnd.ogc.se_inimage&SRS=EPSG:4326&CQL_FILTER=INTERSECTS(the_geom,
querySingle('towns',
'the_geom'))&BBOX=-14.006625976562,44.797148437497,142.12325683594,96.320009765623&WIDTH=1000&HEIGHT=330
I get an exception:
Could not parse CQL ilter list.
Function not found. Parsing: INTERSECTS (the_geom,
querySingle('poppol1000','the_geom')),
What can be wrong here?
