MAInternalEditorComponent and validation

Hi, I'm using MAInternalEditorComponent for editing some complex structures and for now is working ok, but I found a little issue. Take this example: I have a Person, who has an Address. I edit Person for create a new instance, then I run validation for the component... and validation does not validate Address, just it's existence, which obviously exist, because I created it with a #default:, but required values for #street and #number are not chequed. I solved this problem by oberriding #validateSpecific: of MAToOneRelationDescription this way: validateSpecific: anObject super validateSpecific: anObject. anObject description validate: anObject. My question is: is this solution correct? this is maybe a bug of magritte? Thanks, Esteban
