Hi, I've created a vector-to-raster rendering transformation. I have the SLD stored in GeoServer as a style and have added it as an available style to a layer backed by a Shapefile datastore. How do I signify to the SLD to pass in the feature collection from the datastore backing the layer as the feature collection bound to the "flowline_features" input? I would prefer this method (no SLD parameters on the WMS call) so that I can generate WMS output that can be cached using the WMS-integrated GeoWebCache as the rendering may be expensive. When I make calls to the layer with the style an empty feature collection is passed (not null, but a FeatureColletion without any Features).
The WPS process accepts a SimpleFeatureCollection as the ComplexData Input named "flowline_features".
