Django 1.8.7 register decorator didn't work

[stretch4x4]

We had one model that was using the decorator rather than the explicit call and after adding adminplus that model disappeared from our admin screens.

Changing it over to the other call worked although I thought I read that it should have worked so not sure I think there must be a bug there.. Happy to investigate further if someone can point me in the right direction.

Is this a problem with 1.8.7 specifically, i.e. did it work on other 1.8.* versions, or was the upgrade to 1.8.* from another version?

Unfortunately I can't answer that question as we were already on 1.8.7 before we started using adminplus. There is the possibility that the issue is related to our multi app problems but the register did work when I converted from the decorator so I assume something has changed.

I had this same issue, but @athre0z 's solution fixed this for me.
