Description

I have an entity (SimpleEntity) which references an ElementCollection (ChildOne.class). There is a @Strategy annotation on a field within the embeddable class. The first time a query is built for the entity, an exception is thrown:

<openjpa-2.0.0-beta2-r422266:915978 fatal user error> org.apache.openjpa.persistence.ArgumentException: Attempt to map "com.example.ChildOne.address" failed: the owning entity is not mapped.

at org.apache.openjpa.jdbc.meta.MappingInfo.createColumns(MappingInfo.java:558)
at org.apache.openjpa.jdbc.meta.ValueMappingInfo.getColumns(ValueMappingInfo.java:178)
at org.apache.openjpa.jdbc.meta.strats.HandlerStrategies.map(HandlerStrategies.java:65)
at org.apache.openjpa.jdbc.meta.strats.HandlerFieldStrategy.map(HandlerFieldStrategy.java:81)
at org.apache.openjpa.jdbc.meta.FieldMapping.setStrategy(FieldMapping.java:146)
... etc. ...

If the @Strategy is not present, everything works fine. If the exception is intentionally triggered, subsequent use is successful.

Google suggests that this behavior has been seen before <http://marc.info/?l=geronimo-user&m=121545735018232&w=2> and <http://issues.apache.org/jira/browse/OPENJPA-524>, though there appears to have been no resolution in either case and this differs by use of @ElementCollection.
