I don’t understand what you are trying to do. I don’t see any way that factory
components would be relevant in any way to anything you mention.
Suppose you have two normal components implementing MyInterface, and supply
factory configurations for them to create instances as needed, and have a
multivalued reference of type MyInterface. What do you need that this doesn’t
provide?
Thanks
