Thanks Chuck and Jesse. I think I understand the term lazy synchronization and it makes totally sense.
But, how to handle a case like this: Three entities and their relationships: User <-----> Address Client <-----> Address I create a reusable component named EditAddress and use it inside two other components: EditUser and EditClient. I would pass the Address object via a binding. In the EditAddress I would use WOTextFields connected to the address' parameters: address.country, address.state, etc. How could I do that with lazy synchronization? Thanks.
