Hi,
You need to add the "Required" parameter in the RCDC Edit of person, for your custom field:
<my:Control my:Name="Description" my:TypeName="UocTextBox" my:Caption="{Binding Source=schema, Path=Description.DisplayName}" my:RightsLevel="{Binding Source=rights, Path=Description}">
<my:Properties>
<my:Property my:Name="Required" my:Value="{Binding Source=schema, Path=DisplayName.Required}"/>
<my:Property my:Name="Rows" my:Value="3"/>
<my:Property my:Name="Columns" my:Value="60"/>
<my:Property my:Name="MaxLength" my:Value="450"/>
<my:Property my:Name="Text" my:Value="{Binding Source=object, Path=Description, Mode=TwoWay}"/>
</my:Properties>
</my:Control>
You can force the value to "True"
Regards,
