The idea here is that I have a single User login that can eventually be tied to multiple Companies via the Role.

You signup via Devise on the custom /register route and fillout the Company information etc.  The custom registration controller creates the Role during the user creation and sets a few other attributes.

It all worked but now it's broken and I have no idea what I did to break it.

When I try to create a new user / company the additional user fields (name_first & name_last) always fail validation regardless if they are in fact valid.  The nested Company fields do not validate at all.  If I enter the email and password field only the form works but only creates the User record.

To me it seems like the custom registration controller is not being processed at all.
