I've been using 2 different versions of Fusion Pro VDP Designer on 2 different Macs, and getting different Composition reporting results.
I've attached a screenshot to help show this.
With the same project (the Presidio Postcard tutorial actually), using version 9.2.31, I correctly get a Composition error that tells me the "Value for variable Season not found in instance data". This is because the source data doesn't include for the month information, so this makes sense. This is seen on the right screenshot with the attached file.
But, using the latest version (9.3.6) on Yosemite, I don't get that error message even though it fails as well. The error message from the older version is actually quite helpful in troubleshooting, so why is it missing from the latest version of the software? You can see this in the left screenshot.
Is this a bug?
