[jira] Commented: (OPENJPA-496) columns fill wrong entity fields
when names same in joined tables
[ https://issues.apache.org/jira/browse/OPENJPA-496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12645203#action_12645203 ]
Adam Hardy commented on OPENJPA-496:
------------------------------------
Thanks for the info, Milosz. That enabled me to get it working (while watching Obama give his acceptance speech).
So the unit tests which I wrote and attached above fail, but after adapting them to work with some of the OpenJPA unit test base classes, they no longer fail.
I don't have time today to check out what the issue is, but I shall do soon, and I'll report back here, hopefully with a solution so I can mark this issue closed.

> OpenJPA is mixing up the mapping of columns from joined tables, where the two
> tables have fields with the same name used on their respective entities. I've
> got some basic unit tests aimed at verifying the problem. Is there something
> wrong with my mappings or is this a bug? I can upload the unit test project.
> Here's the info. The TITLE fields get mixed up. I have this query:
> select species from Species species
> I have this output:
> SELECT t0.ID, t1.ID, t1.OWNER_ID, t1.TITLE, t0.IUCN_STATUS_ID, t0.OWNER_ID,
> t0.TITLE FROM PUBLIC.SPECIES t0 LEFT OUTER JOIN PUBLIC.GENUS t1 ON t0.GENUS_ID =
> t1.ID
> These are the mappings:
> <entity class="org.permacode.atomictest.domain.Genus">
> <table name="GENUS" />
> <attributes>
> <id name="id">
> <column name="ID" />
> <generated-value strategy="TABLE" generator="genusKeySequence" />
> </id>
> <basic name="title">
> <column name="TITLE" />
> </basic>
> <basic name="ownerId">
> <column name="OWNER_ID" />
> </basic>
> <one-to-many name="species" mapped-by="genus">
> <cascade>
> <cascade-persist />
> <cascade-merge />
> <cascade-refresh />
> </cascade>
> </one-to-many>
> </attributes>
> </entity>
> <entity class="org.permacode.atomictest.domain.Species">
> <table name="SPECIES" />
> <attributes>
> <id name="id">
> <column name="ID" />
> <generated-value strategy="TABLE" generator="speciesKeySequence" />
> </id>
> <basic name="title">
> <column name="TITLE" />
> </basic>
> <basic name="iucnStatus">
> <column name="IUCN_STATUS_ID" />
> <enumerated>ORDINAL</enumerated>
> </basic>
> <basic name="ownerId">
> <column name="OWNER_ID" />
> </basic>
> <many-to-one name="genus">
> <join-column name="GENUS_ID" />
> </many-to-one>
> </attributes>
> </entity>
