Passing a contract to a modal

[ju5t]

We have a Customer and Supplier model that both implement an Addressable contract. Adding and editing addresses will be done through a modal. This won't be easy as we often only pass the id of a model to it. That's not be possible here.

There are a few ways I can think of:

• Pass the class name and init it manually in the modal, but it's unsafe.
• Use an Enum to identify the addressable object and pass its value. This is safer, but prone to errors when you add more Addressable implementations.

Are there any other safe ways to pass an Addressable implementation to this modal without exposing too much data?
