Re: [udig-devel] filtering contents of rendered layers
|
Hmmm. I think you found a little bug with my logic. I need the
datastore in order to create the view and I do that through the
service. I could change it to access the datastore using the
FeatureSource instead... That would be a good idea.
But unless you want to make that change you might consider changing
your service to return a Datastore... Unless you can't for some
reason, in which case you'll want to use create a custom style for
this functionality.

Put a break point in ShowViewInterceptor and verify that the filter

Hmm, no it's not. The 'properties' member of LayerImpl is empty.
Why would that be?
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).
Vince.
