[forge-dev] Scaffolding immutable JPA entities

This is happening because you can't use the entity it self as "data entry" model 
to pass to criterias/queries etc ? 

Could it make sense to have a way to fallback on to map based approach for search criterias
which are not mapped to strongly typed classes when you are dealing with such immutable types
(or rather entities without setters) ?

The generated scaffold does not allow creation of the constituent immutable types (obviously) along with the root JPA entity. Additionally, if these root JPA entities contain Bean Validation constraints on the immutable types, then creation or updation of these entities would fail depending on what constraints are imposed.

Obviously, it makes little sense to also prevent scaffolds from being generated for JPA entities composed of immutable types. Also, this makes revisit FORGE-917 - should we revisit the design of the generated managed (view)beans to support immutable types?
