[Teneo] single join table for mtm results in exception [message #79743]

Martin,

I updated my model so all many-to-many relationships include the
annotation for setting indexed=false. The resulting database tables look
great. I loaded my data and saved into the database with no problem.

However, when I try to access objects via these single join tables I get
Hibernate exceptions that state the indexed column is NULL, etc.

The mapping file for one of these looks like...

<bag name="contacts" lazy="true"
cascade="merge,persist,save-update,lock,refresh" table="`service_contact`">
<key update="true">
<column name="`service_e_id`" not-null="true" unique="false"/>
</key>
<many-to-many entity-name="Contact" unique="false">
<column name="`contact_e_id`" not-null="true" unique="false"/>
</many-to-many>
</bag>

and ....

<bag name="services" lazy="true"
cascade="merge,persist,save-update,lock,refresh" inverse="true"
table="`service_contact`">
<key update="true">
<column name="`contact_e_id`" not-null="true" unique="false"/>
</key>
<many-to-many entity-name="Service" unique="false">
<column name="`service_e_id`" not-null="true" unique="false"/>
</many-to-many>
</bag>

Any ideas...?

Thanks,
Mark.

Mark,
The mapping looks fine, can you post the stack trace?
The exception is thrown for a specific many-to-many probably, can you check which one it is and
check the mapping for that specific many-to-many?

Martin,

The mapping file for the relationship looks fine. In fact, all the mtm
relationships look the same.

Here is the stack....

Martin,

Don't spend any time on this. It looks like I had an old copy of the
hibernate.hbm.xml file, which is the one used, that caused the schema
change.

I am re-creating and re-loading the data to verify.

Assuming that I am correct sorry for the wild goose chase....

Mark.
