You might want to add '<None>' to your list. The problem is when the dropdown

is first init - it does not have any data - therefore the need to have a null

value. In Dabo the null value is converted to the string '<None>'.

But now that you have gotten this far - try the other ways to populate a

dropdown. They will offer more control and better results than hard coding

the 'Choices'.
