Monorail Excpetion, "The given key was not present in the dictionary."

I am quite blocked about an exception.

I am using Active Record and Monorail. I was able to use the scaffold controllers in monorail, until I add new models.

System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

Here is all the sourcecode: http://bitbucket.org/mariocesar/mangos/src

By Example, for the model Inventory.Product there is the ProductsController, it Work until I add some relations.

I don't understand if the problem is in NHibernate, or if can't be Scaffold, or if the problem is ActivRecord.

A hint, would be nice

I found the problem, was a Missing Active Record declaration.
