Hi Viv,

OK... I removed the SelectedValue section and re-ran a test. I now see data being displayed in the combo, but it is the first item in the entity list. It looks like we've gotten one step closer (at least I see something now). But the combo box is not being synchronized with the business object when the form opens up.

<ComboBox x:Name="cboActions" DisplayMemberPath="ActionName" SelectedValuePath="ActionCode"
