OK, what should I name it instead of status? I can't find it in the doc.

I think StateModel is deprecated stuff (only works if a field is named state, I might be wrong on that one). But to answer your question:
You can name field whatever you like, as long as it's a StateField.
Basically don't use a StateModel at all, and that's it.

Thanks for your answer
