Andy Jefferson commented on JDO-403:
------------------------------------
> 2. I'd like to talk about mapping org.apache.jdo.tck.pc.mylib.PCRect as an embedded field. PCRect includes
> two PCPoint instances, so you have to map the embedded PCPoint instances as embedded-embedded
Agreed - nested embedded PC fields aren't catered for in what was provided, and your example (but using PCRect/PCPoint as nested embedded) demonstrates how it could be done for 1-level of nesting. XML handles this fine since you can have <embedded> within
a <field> recursively (down to multiple levels). Annotations have some strange limitation on recursing too (in addition to the other strange limitations), so not sure if you'll be able to get multi-level recursion (like XML supports). Its the same issue
we have with @FetchGroup and @FetchField

> Key: JDO-403
> URL: https://issues.apache.org/jira/browse/JDO-403
> Project: JDO
> Issue Type: New Feature
> Components: api2
> Affects Versions: JDO 2 final
> Reporter: Andy Jefferson
> Assignee: Michelle Caisse
> Fix For: JDO 2 maintenance release 1
>
> Attachments: embedded.patch, jdo_2_1_annotations.jar

> It would be desirable for JDO2 to have its own set of annotations. We have developed a set within JPOX that would likely serve as a starting point for such a set. In my opinion they should be
> 1. Split into javax.jdo.annotations.jdo and javax.jdo.annotations.orm
> 2. Move ORM attributes from some of the JDO annotations and have a ORM annotation.
