I'm adding a child BO that will be called similar to the childBO in your CRM example. Somewhere along the way after I added the child object to the form and configured my second child BO relationship by the primary key(case_sid) I get the following exception when adding a new record:

SyntaxErrorException

            Syntax error: Missing operand after 'case_sid' operator.

All of my fields are locked on the form until I either remove the childBO from my maintenance form or eliminate the relationship with the Parent BO. In the mean time I've added my third business object without error. The issue is probably some tweak of the object, but I cant figure it out. I thought the exception might be familar to you.

Second there might be issues with the underlying database changing keys, so I deleted the object and it's mapping. Dropped and rebuilt the database table and am in the process of reviewing.

The primaryKey of Parent table is: caseid this is the also the FK in my child objects

I check if parent records exist before populating the children:

Private Sub Cite1_Navigated(ByVal e As MicroFour.StrataFrame.Business.NavigatedEventArgs) Handles Cite1.Navigated

     '-- Make sure there are records in the citation BO, otherwise
     ' an error will occur.

     If Cite1.Count > 0 Then
     '-- Load the childBOs
          Me.Driver1.FillByParentPrimaryKey(Cite1.case_sid)
          Me.Officer1.FillByParentPrimaryKey(Cite1.case_sid)
          Me.Violations1.FillByParentPrimaryKey(Cite1.case_sid)
     '-- Requery the officer list
          Me.lstOfficers.Requery()
     End If

End Sub

Note my first child object Driver1 is working properly. Working with Trent we set the following settings on the Parent object Cite1 and the Driver child object.

IncludeFormAdd: True
IncludeFormEdit: True
IncludeFormDelete: True
IncludeFormSave: True

Would these setting affect workings of the two new child objects I'm trying to add?
