I want to join two feature types in my WFS in a union. How can I achieve this using CQL? E.g.
http://localhost:8080/example/ows? service=WFS& version=2.0.0& request=GetFeature& srsName=epsg:4283& typeNames=type1,type2&
This returns an error:
Join query must specify a filter
I'm trying to append a cql_filter parameter, but the ones I try don't work.
What filter can I use to grab both types, in any format?
