Breaking changes between build 642 and 644
Asger Hallas
via web
I'm not exactly sure what happened between these two builds, and I have not been able to figure it out from the logs. But mapping my small entity hierarchy is suddenly failing with a
"System.InvalidOperationException: Tried to add many-to-one 'Case' when already added."
I have attached a failing test-case. It works using 642, but every build after that breaks it.
Have something essential changed? Or am I doing something incorrectly?
Cheers,
Asger

I moved around a load of the automapping stuff recently, quite possibly
between those builds, but I was unaware of any breaking changes. I guess
there's something we haven't got covered by tests.
Could you attach your the entity(s) in question, and show us how you're
setting up the automapper. We'll try to replicate the issue.

Thanks for quick reply. Entities and setup is in the attached zip-file. It's stripped down to only include the minimum possible to obtain the exception. Do you want it another way? I'll be happy to supply it in any other form too :)

Sorry, I missed that you'd already attached it! You're obviously sharper than me in a morning.
I'll take a look at your issue as soon as possible.

Well, I guess I had about one hour more than you to wake in, giving I'm at GMT+1 :)
Thank you!

I've just pushed a fix for this up to github. I'd appreciate if you could get the latest version and see if you have any issues with it.

That's good news! Just checked it out and everything works like a charm.
Thank you very much. And have a good day :)
