I am wanting to use Null in a Power Filter and I see that this is not available in v.12, which is what we're using now. We are upgrading to v.13 soon and are testing it now. I don't see that v.13 has that capability either. Could you please confirm? If v.13 can do it, what would the syntax be? I am trying to filter for null values on a numeric field which ranges from 0-100. How do I specify NULL? Thanks.
