I am using it with good results. I have a many-to-many relationship between a ProductRevision table and a Risk table. The association table has three columns: prod_risk_id, prod_rev_id, risk_id. prod_risk_id is an unnecessary primary key I am using because I don't like multi-column pk values. Here is my mapping for the association table:

Code:
   <idbag name="risks" table="hmmtb_product_risk">
       <collection-id column="prod_risk_id" type="int">
          <generator class="edu.mayo.gensupp.hmm.util.GSFMultipleHiLoPerTableGenerator">
              <param name="table">hmmtb_next_id</param>
              <param name="primary_key_column">nxt_pk_col</param>
              <param name="value_column">nxt_pk_value</param>
              <param name="primary_key_value">prod_risk_id</param>
              <param name="primary_key_length">30</param>
          </generator>
       </collection-id>
       <key column="prod_rev_id"/>
       <!-- mapped with outer join tag because hibernate docs example had it -->
       <many-to-many column="risk_id" class="Risk" outer-join="true"/>
   </idbag>


This is in the ProductRevision mapping file.
