Issue #2210
resolved
Hi,
I think I've come across a regression in 0.7.1 compared to 0.7.0. I'm getting the error below with 0.7.1 but with 0.7.0 all is fine.
I could try to reduce this to a test case but since I'm currently short on time I was hoping that by looking at the error message you can tell what's wrong. Please let me know if you need anything else.

This is a mapped class such as
Job
