The problem is that when using an MAInternalEditorComponent you want the validation you added. When using an MAExternalEditorComponent you don't want it though, as the model already validated in the external editor. Otherwise you run into strange bugs. Frankly I never use (or used) these internal and external editors in productive applications. This seems simply to complicated to make it work in properly in all situations. When it comes to relationships I usually do write some glue code by hand. Often this turns out more user-friendly than an generated form too. Cheers, Lukas
