I'm following this guide but I'm getting errors when I try to load the attributes or modigy them. Also when I load any product with attributes.
I don't know why that happends, I'm getting this error:
[ConstraintException: The 'bloquear' property on 'ProductAttributeMapping' could not be set to a 'null' value. You must set this property to a non-null value of type 'System.Boolean'. ]

I followed that guide, but I don't know if I'm forgetting some file because this is a little bit more complex than the category one. Thanks for your attention
