Angular Web: If a validation scripts ViException affects a request property parameter which is Multivalue and using the EditFkMultiComponent, the WebPortal doesn't show an error message (4383562)

Angular Web: If a validation scripts ViException affects a request property parameter which is Multivalue and using the EditFkMultiComponent, the WebPortal doesn't show an error message

We use the following code in our validation script:

Dim str As String = Convert.ToString(Value)

If Not String.IsNullOrEmpty(str) Then
Dim mvp As New MultiValueProperty(str)

For Each prop In mvp
Dim profitCenter As IEntity = Session.Source.Get("ProfitCenter", prop, EntityLoadType.ReadOnly)
Dim costObjectType As String = profitCenter.GetValue("CCC_CostObjectType").String

If String.Equals(costObjectType, "Cost Node", StringComparison.OrdinalIgnoreCase) Then
Throw New ViException(#LD("You cannot select cost nodes (e.g. {0})", profitCenter.Display)#, ExceptionRelevance.EndUser)
End If
Next
End If

The exception only shows in the javascript console output, but no frontend messagebox is shown.
