Within a XamDataCards control via xaml I can add a Infragistics.Controls.Editors.XamComboEditor like so...

<dataPresenter:XamDataCards Name="dataCards" Theme="Aero">

<ig:XamComboEditor Name="xamComboEditor1"
VerticalAlignment="Top"
AllowMultipleSelection="True"
CheckBoxVisibility="Visible"
DisplayMemberPath="LastName"
ItemsSource="{Binding}" />
</dataPresenter:XamDataCards>

But I cannot add it as a field via the field layouts, it results in a runtime exception of "FieldSettings.EditorType's must be set to a type that derives from ValueEditor\r\nParameter name: EditorType"...

<dataPresenter:XamDataCards Name="dataCards" Theme="Aero">
<dataPresenter:FieldLayout>
<dataPresenter:FieldLayout.Fields>
<dataPresenter:UnboundField Name="xamComboEditor1">
<dataPresenter:Field.Settings>
<dataPresenter:FieldSettings EditorType="{x:Type editors:XamComboEditor}">
<dataPresenter:FieldSettings.EditorStyle>
<Style TargetType="{x:Type editors:XamComboEditor}">
<Setter Property="ItemsSource" Value="{Binding}" />
<Setter Property="DisplayMemberPath" Value="LastName" />
<Setter Property="CheckBoxVisibility" Value="Visible" />
<Setter Property="AllowMultipleSelection" Value="True" />
<Setter Property="VerticalAlignment" Value="Top" />
</Style>
</dataPresenter:FieldSettings.EditorStyle>
</dataPresenter:FieldSettings>
</dataPresenter:Field.Settings>
</dataPresenter:UnboundField>
</dataPresenter:FieldLayout.Fields>
</dataPresenter:FieldLayout>
</dataPresenter:XamDataCards>

Is there any way to make this possible or a work around to allow the editor to be added via the field layouts?

Thank you,

Jonathan
