Robert,

>I have a combobox with all properties set as stated in the "Jump Start". When I save the "BindingValueSource" business object all fields are filled in as expected, but my FK field gets replaced with the number 0 instead of retaining the value that was passed when the save began.

I'm only adding one record and thats to the "BindingValueSource" business object. When I get to "mmBusinessForm.cs" and look at the "bizObj" it has all the values I'm expecting. When it gets to:

Is this a Windows or Web app? Can you post the values you are using for the MM .NET binding properties?
