It wasn't the Mode that I wondered about but rather the way you were setting the Binding. Before you had "Binding Path=Action" and I suggested just "Binding Action"
I am not sure about why it is not adjusting to the proper value, but it may be a property of the business object. Let me check on that.

I swear it was not doing this before. It wouldn't display a thing unless I forced a value into the SelectedIndex. Nevertheless, It seems like it's almost working correctly now. I just need the combobox to display the correct value upon first view of the window.
