Hi Tim,

I've tried with Mode=Default, and TwoWay. I just retried it to make sure. Same result. I'm leaving it as Default for now.

However, after I put the SelectedValue section back in place (after trying Viv's first suggestion) I now notice that the combobox is regularly showing a value upon first view of the window -- although it's simply the first item in the list and is not synchronized with the primary business object's true value. 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.

???
