-----------------------------------------
Summary: Document and annotate @DomainObject, @ViewModel and
@Mixin with @Scope(SCOPE_PROTOTYPE)
Key: ISIS-2270
URL: https://issues.apache.org/jira/browse/ISIS-2270
Project: Isis
Issue Type: Improvement
Reporter: Daniel Keir Haywood
Assignee: Daniel Keir Haywood
Fix For: 2.0.0
We want Spring to discover these types from the classpath (so that we can build
the metamodel eagerly), but we don't want it to manage them.
Using @Scope(PROTOTYPE) is the closest we can come to expressing that without
(attempting to) define a custom scope for each of these three types., analogous
to factoryService#instantiate for transient objects.
In practical terms, inventing a custom "entity" scope is probably impossible
due to DN's design (the enhancer creates a dnNewInstance method and this is
called upon as a factory).
Instead, then, we "veto" any of these domain types so that Spring is NOT
allowed to instantiate any of them.
The docs should be updated to explain what we're doing here.
