Rick Curtis reopened OPENJPA-859:
---------------------------------
> OpenJPA requires all persistent fields to be specified on an XML defined
> entity
> -------------------------------------------------------------------------------
>
> Key: OPENJPA-859
> URL: https://issues.apache.org/jira/browse/OPENJPA-859
> Project: OpenJPA
> Issue Type: Bug
> Components: jpa
> Affects Versions: 2.0.0-M2
> Reporter: Jeremy Bauer
> Assignee: Rick Curtis
> Fix For: 1.3.0, 2.0.0-M3
>
>
> This problem was reported by Frank Schwarz on the user forum[1]. It appeared
> to be related to the use of the new element-collection element in XML, but is
> actually are result of not having all persistent fields defined in XML. If
> all fields are defined - or the entity is simply annotated with @Entity no
> exception is thrown.
> Based on the JPA spec:
> 2.1.1 - If the entity has field-based access, the persistence provider
> runtime accesses instance variables
> directly. All non-transient instance variables that are not annotated with
> the Transient
> annotation are persistent. When field-based access is used, the
> object/relational mapping annotations
> for the entity class annotate the instance variables.
> In addition, the <entity> xsd documentation states: [entity] Defines the
> settings and mappings for an entity. Is allowed to be
> sparsely populated and used in conjunction with the annotations.
