Hello!
Little hard to read the mappings, but I encountered kind of same.
With this mapping:
<class name="BlockKurskatalog" dynamic-insert="true" dynamic-
update="true" >
<id name="ID" column="collection_index" type="Int32" >
<generator class="hilo"/>
</id>
<property name="BlockId" not-null="true" />
<property name="KurskatalogId" not-null="true" />
<many-to-one name="Block" column="Block_id" class="Block"
cascade="save-update"/>
<many-to-one name="Kurskatalog" column="Kurskatalog_id"
class="Kurskatalog" cascade="save-update"/>
</class>
So doing like this
So when having a object of this type associated with the session and
setting one of the many-to-one properties and the same property mapped
to the same column produced the
same error as you encountered,
Hope this is helpful.
