[GIS] GeoServer cascading WMS, FeatureInfo is lost

geoservergetfeatureinfowms

I'm trying to cascade a WMS service in GeoServer (http://grb.agiv.be/geodiensten/raadpleegdiensten/GRB/wms?REQUEST=GetCapabilities&SERVICE=WMS).

I can view the cascaded layers just fine, but whenever I try to get FeatureInfo from a cascaded layer I get an error message saying that the layer isn't queryable.

I can get the FeatureInfo from the original service, so I know that there is actual FeatureInfo on the original layers.

I've combed through every available WMS setting in GeoServer but only found the 'Queryable' option in the 'WMS Settings' panel in the Publishing tab of the cascaded layers, which is obviously enabled.

Is there anything I'm missing, or is it just not possible to get FeatureInfo from a cascaded WMS service?

According to the documentation:

GetFeatureInfo cascading for servers that do support the application/vnd.ogc.gml feature info format. Works in both standard and reprojected case.

It seems that your server does provide that format but I haven't actually tested that it does. You may need to make sure that your request is also in that format?

So the bottom line is that it should be working - can you check what the request that is sent to the remote server looks like (may be with wireshark if you don't have access to the remote logs).
