I generated the business object with the BLG, so it is automatically numbering each entity. So I don't understand why it would say that this field needs to be unique, when it is doing the actual generating of the key value. The field is setup as an identity field on the backend. Does the business object entitylist support 258 entity items? What would cause an auto incremented field to throw this error?

What happens when you try to save a single record to the same database table? I am not aware of a limitation on the EntityList and I suspect something else.
