ADXBackstageDropDown Change Event broken if items added at runtime

I'm developing a Word 2010 add-in in which I need to rework/replace the Backstage tab for Printing with own controls to check the printer the user has selected while printing.
I'm reading the printers from the registry and populate a BackstageDropDown control with the values in the OnShow event of the backstage tab. I need the OnChange event to change the current printer to the selected one from the dropdown.

Unfortunately, the OnChange event is broken *if the items in the dropdown are added at runtime*. If I add them at design-time, the OnChange fires correctly.
I've started with a Combobox instead of a Dropdown. With a Combobox control, there is no difference, and the OnChange event fires correctly. But the Combobox cannot be set to "readonly" style, so the user may type in nonsense, so I changed it to a dropdown control.

I've sent a sample Word 2010 add-in reproducing the issue to the ADX support e-mail address referring to the subject of the topic.

It seems to be a bug in ADX. Please advise. If you have an idea of a workaround, it would be great.

Here's a screen shot of the backstage tab. On each change event, the label control below the dropdown or combobox should be updated with the selected value.

Hi Peter,

There is no bug. You just need to specify the Id property for all your backstage view controls. For example: 

Private Sub FillDropDown1()
   Dim adxitem As AddinExpress.MSO.ADXBackstageItem
   Dim i As Integer
   With Me.AdxBackstageDropDown1.Items
       For i = 1 To 5
           adxitem = New AddinExpress.MSO.ADXBackstageItem
           adxitem.Caption = "BackstageItem - Dropdown " & i
           adxitem.Id = "adxBackstageItem_3c2d387ffa144f1fb2e58eb0f37cb61" + i.ToString()
           .Add(adxitem)
       Next
   End With
   Me.AdxBackstageDropDown1.SelectedItemIndex = 0
End Sub

Thank you very much, Eugene,
I've just tried it out in my add-in and it works now like a charm. Great!
