Missing join clause in query with collection-table with two join-columns
------------------------------------------------------------------------
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
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.
