Hi All -
I have a Set collection mapped with a composite-element.

I'm using spring, and after each session.load(), the session is flushed.

With this collection, during the flush the collection is deemed dirty, which causes a chain reaction of updates and cache invalidations that I don't want.

Any suggestions on what is making this collection be interpreted as dirty on every load?

the mapping for this set looks like:
Code:
       <set
            name="invitationAddlContacts"
            table="INVITATION_ADDL_CONTACT"
            lazy="false"
            inverse="true"
            cascade="all"
            sort="unsorted"
        >
            <cache
                usage="nonstrict-read-write"
             />

              <key
                  column="INVITATION_ID"
              />

              <composite-element
                  class="com.benefitpoint.cmp.marketing.invitation.InvitationAddlContact"
              >
        <property
            name="email"
            type="java.lang.String"
            update="true"
            insert="true"
            column="EMAIL_ADDR"
        />

        <property
            name="firstname"
            type="java.lang.String"
            update="true"
            insert="true"
            column="FIRST_NAME"
        />

        <property
            name="lastname"
            type="java.lang.String"
            update="true"
            insert="true"
            column="LAST_NAME"
        />

              </composite-element>

        </set>


my hibernate log looks like:

Bad equals/hashCode implementation?
