Hi,
I tried to verify the situation of http://jira.codehaus.org/browse/GEOS-3860 with GS 2.7-RC1 hoping that I could close the ticket. However, I could not make cascading to work by using server URL http://demo.opengeo.org/geoserver/ows?service=wfs&version=1.1.0&request=GetCapabilities
Could somebody with more experience have another try?
