When I try to add a new record to my business object, I am getting the following error.  The business object has records in it, and I can access the primary key field in debug.  I can edit and save a record, just can't add new.  Not sure what the problem is here, but please offer a suggestion.

There should be an inner exception that will contain more detailed information.  Most likely, the parent business object does not have any records in it, and so you cannot add a record to the child because the child business object is trying to maintain the relationship to the parent. 

Check the inner exception.  If it says something like "could not evaluate current row Count:0, CurrentRowIndex: -1 then there is no parent record for the children you are trying to add.
