Does Not Work with Mongoid 5

[rdetert]

Mongoid 5 is required for MongoDB 3 (the latest version). AASM doesn't seem to work with Mongoid 5.

Here is a test project: https://github.com/rdetert/aasmtest
Use the model tester.rb.

To see the error type:
$ rails c
2.1.5 :001 > Tester.drafting

If you revert the Gemfile back to Mongoid 4, the error goes away.

Here is the error:

@rdetert You are right. AASM's tests have errors as well with version 5. Thanks for pointing that out!

I just released version 4.4.0 including a patch.
