Subject [jira] Created: (OPENJPA-1107) Provide TraversableResolver for use with Bean Validation Factory

Provide TraversableResolver for use with Bean Validation Factory

                 Key: OPENJPA-1107
             Project: OpenJPA
          Issue Type: Sub-task
          Components: validation
    Affects Versions: 2.0.0
            Reporter: Jeremy Bauer
            Assignee: Jeremy Bauer

Per the JPA 2.0 specification, a TraversableResolver must be provided in order to meet the
validation criteria outlined in section of the 3/13/09 draft.

The validator instance that is used for automatic validation upon lifecycle events must use
a TraversableResolver
that has the following behavior:
• Attributes that have not been loaded must not be loaded.
• Entity associations (single-valued or multi-valued) must not be traversed.

These requirements guarantee that no unloaded attribute or association will be loaded by side
effect and
that no entity will be validated more than once.
Embeddable attributes must be validated only if the Valid annotation has been specified on
It is the responsibility of the persistence provider to pass an instance implementing the
TraversableResolver interface to the Bean Validation provider by calling ValidatorFactory.
