Sorry to correct myself, but sometimes it does seem to be picked up 
correctly.  Not sure of the difference, but it does seem to be there 
just before rendering.  But, what seems to happen then:

                    IService service = (IService) parent;
                    DataStore ds=service.resolve(DataStore.class, 
ProgressManager.instance().get());
                    if( ds==null )
                        return resource;
                    FeatureSource view;
                    if( prop instanceof Filter )
...

is that 'ds' is null, since our service is just following the 
documentation of IService.resolve() which doesn't mention any need to 
support returning a DataStore.

Is that going to be the issue? (since the code immediately after the 
'return' above is where the Filter seems to be applied to get a view).
