>
> Key: OPENJPA-1893
> URL: https://issues.apache.org/jira/browse/OPENJPA-1893
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 2.0.1
> Reporter: Patrice DUROUX
> Assignee: Fay Wang
> Attachments: Attribute.java, Feature.java, FeatureId.java
>
>
> Considering the following mapping:
> <entity class="Feature">
> <table name="features" />
> <attributes>
> <embedded-id name="id" />
> <element-collection name="attributes">
> <collection-table name="qualifiers" />
> </element-collection>
> </attributes>
> </entity>
> Without specifying any JoinColumn element in the CollectionTable element, I got the query:
> (...) INNER JOIN qualifiers t3 ON t0.index = t3.FEATURE_INDEX AND t0.oid = t3.FEATURE_OID (...)
> but changing the mapping by:
> <collection-table name="qualifiers">
> <join-column name="oid" />
> <join-column name="index" />
> </collection-table>
> I got:
> (...) INNER JOIN qualifiers t3 ON t0.index = t3.index (...)
> where is missing the first JoinColumn.
