I'm declaring a set with fot many-to-may association with:

Code:

   <set name="assuntos" table="apoloes.ProcessoAssuntoProcesso" lazy="true" order-by="NUMORD">
      <key>
         <column name="CODSECAO"/>
         <column name="CODDOC"/>
      </key>
      <many-to-many class="br.gov.trf2.jfes.apolo.processo.AssuntoProcesso">
         <column name="CODSECAO"/>
         <column name="CODASSPROC"/>
      </many-to-many>
   </set>

As you can see, CODSECAO is a common column to tables Processo, AssuntoProcesso and ProcessoAssuntoProcesso.

the following exception occur

org.hibernate.MappingException: Repeated column in mapping for collection: br.gov.trf2.jfes.apolo.processo.Processo.assuntos column: CODSECAO

How can I make the mapping without errors?
