[Forums] Combo box doesn't respect default value when no item is selected

Thank you for your reply

I am not sure if I can solve the problem by merely test for 0 or NullIdentifier() because the thing is, that when the combo box is populated, I actually have a record with the value of 0 coming from the database. If I test for 0, I will get two results, the one from the special list, and the existing record too.

What should I do in this case?

Thank you
