    I'm glad you fixed it, do you have a workaround I can use until 8.3.5 is released?

      Hello Robert,
      Yes, currently, to work around you can manually edit the designer file of your module. For instance, you can add the following code in the InitializeComponent method of the MainDemoModule class in the MainDemoModule.Designer.cs file:

      C#
      private void InitializeComponent() {  
//...  
    this.RequiredModuleTypes.Add(typeof(DevExpress.ExpressApp.Validation.ValidationModule));  
//...  
}  
      Visual Basic
      Private Sub InitializeComponent()  
'...  
    Me.RequiredModuleTypes.Add(GetType(DevExpress.ExpressApp.Validation.ValidationModule))  
'...  
End Sub

      Thanks,
      Dennis
