       Body:
That line of code is correct.

Are you *sure* that your composite element class implements equals() / hashCode() correctly, as is required by the Set contract?

I doubt that there is a bug in Set....

Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-124
    Summary: Hibernate thinks unmodified <set> of value objects is dirty
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.0 final

Environment: Win2k

Description:
Hibernate thinks that a collection of value objects is modified when it really isn't. It tries to save it to the DB everytime it is loaded.

This line from Set.snapshot looks suspect:

clonedSet.put(copied, copied);

Shouldn't the key be the original value - not the copy?


Here is an excerpt of my mapping file:

  				<set name="timeRanges" table="FTGO_RESTAURANT_TIME_RANGE" cascade="all">
					<key column="RESTAURANT_ID"/> 
						<composite-element class="net.chrisrichardson.foodToGo.order.hibernateImpl.HibernateTimeRange"> 
		                <property name="dayOfWeek" column="day_Of_Week"/>
		                <property name="openHour" column="open_Hour"/>
		                <property name="openMinute" column="open_Minute"/>
		                <property name="closeHour" column="close_Hour"/>
		                <property name="closeMinute" column="close_Minute"/>
				    </composite-element>
 				</set>
