I'm having problems of kind "you may not dereference a collection with cascade=all-delete-orphan". I've read something about, but my issue is a little different. It occurs when I try retrieving some objects from db, and it occurs randomly with a few queries. When I do a simple search, the exception occurs, if I try the search right after, the result come normally. Remenbering, I am just doing a simple search, not trying change the collection.

Hibernate 2.1.4

Mapping
Code:
 
...
      <bag
            name="garantias"
            lazy="true"
            cascade="all-delete-orphan"
        >

            <key
                column="id_equipamento"
            >
            </key>

            <one-to-many
                  class="br.com.inovar.gif.dominio.GarantiasFornecedor"
            />

      </bag>

        <list
            name="itens"
            table="equipamentos_item"
            lazy="true"
            cascade="none"
        >

            <key
                column="id_equipamento"
            >
            </key>

            <index
                column="ordem"
            />

            <many-to-many
                class="br.com.inovar.gif.dominio.Item"
                column="id_item"
                outer-join="auto"
             />

        </list>

        <set
            name="valoresCaracteristicos"
            lazy="true"
            cascade="all-delete-orphan"

        >

            <key

            >
            </key>

            <one-to-many
                  class="br.com.inovar.gif.dominio.ValorCaracteristico"
            />

        </set>

        <bag
            name="locacao"
            lazy="true"
            cascade="all-delete-orphan"
        >

            <key
