Hi,

This goes back to
http://www.eclipse.org/forums/index.php?t=msg&th=197763& amp;start=0&S=7751083adf9c63f5ab45e02873e5e156

I have a simple one-to-many relation and would like to generate a simple
orm.xml like this:

On the one-side:

<orm:one-to-many mapped-by="project"
target-entity="ch.arenae.projectcontrolling.core.Rapport" />

On the many-side:
<orm:many-to-one name="project"
target-entity="ch.arenae.projectcontrolling.core.Project">
<orm:join-column name="P_ID"/>
</orm:many-to-one>

But instead Texo generates a join-column element on the one-side:
<orm:one-to-many mapped-by="project" name="rapporte"
target-entity="ch.arenae.projectcontrolling.core.Rapport">
<orm:order-by></orm:order-by>
<orm:order-column/>
<orm:map-key-convert></orm:map-key-convert>
<orm:join-table name="Project_rapporte"/>
<orm:cascade>
<orm:cascade-persist/>
<orm:cascade-merge/>
<orm:cascade-refresh/>
</orm:cascade>
</orm:one-to-many>

How can I get rid of this?

Best regards,
Peter

Hi Peter,
You can annotate this specific association to use a join column instead of a jointable, or if you want all
non-containment associations to not-use a join table add an epackage annotation and set the eattribute
useJoinTablesForNonContainment to false.
See here for info on how to set annotations for the model:
