Dear Andrea,
unfortunately the geoserver instance I'm running is deployed on a machine not available to the public (we are under a secured proxy).
But I deployed the stable geoserver war and to do my tests I added as wms store the wms of my geoserver (i.e. the capabilities url is:  http://localhost:8080/geoserver/wms?service=wms&request=GetCapabilities).
Could this be useful for your test?

Cheers,
Marianna

Hi,
I have done the following steps:
1) creation of a new WMS store
2) publish of one of its layer
3) preview of this layer
The third action produces the exception: "Error rendering coverage on the fast path java.lang.NullPointerException null"

WMS cascading is pretty new, it has been tested with GeoServer and MapServer instances so far.
Judging by the stack trace it seems GeoServer has troubles parsing the capabilities document of that cascaded
WMS.
Is the server available to the public? To see what's going on we need to debug GS as it tries to cascade that server


Cheers
Andrea
