Hi Ricardo,

I think Anjo's reply was in regards to postponed validation, not your issue 
with ERDEditOwnedRelationship.  I'm honestly not sure why you're getting 
validation errors with that component, because I've never actually used it.  
Try searching the list, I've heard David LeBer mention it a time or two.  

That said, have you tried an edit fault component instead?

That will take you to an edit relationship page where I can attest that 
mandatory relationships for newly created EOs works just fine.  

As for making the owns relationship mandatory vs. optional, there was some 
discussion regarding this back in March.  You might find the discussion 
interesting.
