on the if statement
you guessed right this.DefaultValues is an undefined value. Is that the same as null?
Where would I assign a value to this.DefaultValues OR am I testing the wrong thing?

Would you believe I don't know... what is the line of code in the Jump Start that saves the business object? Where would/should it be?

Yes the CheckForDuplicateICDACode code gets executed...

Thanks for your help, sorry I am so clueless... Dave
