Wouter Zoons commented on HIB-82:
---------------------------------
In particular it appears to affect all many-to-many self-associations, of which
we have a few, nothing special about them - navigable in only one direction.
We were getting mapping code that looked like this (sorry if this is confusing):
<set name="seeAlso" table="SEE_ALSO" order-by="SEE_ALSO_FK" outer-join="auto"
lazy="true" inverse="false">
<key foreign-key="BIBLIOGRAPHIC_REFERENCE_SEE_ALSO_FKC">
<column name="BIBLIOGRAPHIC_REFERENCES_FK"/>
</key>
<many-to-many
class="edu.columbia.gemma.common.description.BibliographicReferenceImpl"
column="SEE_ALSO_FK" foreign-key="BIBLIOGRAPHIC_REFERENCE_SEE_ALSO_FKC"/>
</set>
I think BIBLIOGRAPHIC_REFERENCE_SEE_ALSO_FKC should not be used twice? I see
you changed it from 'sourceEnd' to 'otherEnd' in the first instance. The
SEE_ALSO table ends up with two foreign key constraints with the same name.
> foreign key constraint name cause SchemaExport error
