NHibernate many-to-many relationship does not update join-table
- by Davide Vosti
I'm having trouble saving a many-to-many relationship with nhibernate. I searched and looked at almost every same question in SO and google but nothing works.
The single classes are update correctly but nothing is inserted in the join-table.
I have 2 classes: Event and Category.
The mapping is this:
Event:
<bag name="Categories" access="field.camelcase-underscore" table="EventCategories" inverse="true" cascade="all-delete-orphan" lazy="true">
<key column="Event"/>
<many-to-many class="Category" column="Category"/>
</bag>
Category:
<bag name="Events" table="EventCategories" access="field.camelcase-underscore" cascade="all-delete-orphan" lazy="true" >
<key column="Category"/>
<many-to-many class="Event" column="Event"/>
</bag>
I tried to swap every parameter in both mappings but nothing works...
Do you know what I'm doing wrong or have a right mapping for this case?
Thank you very much!
