 Post subject: Different results

I have the folowing set defined in an entity called Host:
================================================
<set name="serviceStatuses" lazy="false">
<key column="host_name"/>
<one-to-many class="com.contego.arx.domain.Service"/>
</set>
================================================

When I let Hibernate automatically populate this Set it returns 1 result (incorrect number).

When I perform a find I get 2 results (correct number) using the following code:
================================================
getSession()
.createCriteria( Service.class )
.add( Expression.eq( "hostname", h.getHostname() ) )
.list()
================================================

Any ideas why this would return different results?

Thanks,

Chris

Need to see the whole mapping for the class defining:
<set name="serviceStatuses" lazy="false">
<key column="host_name"/>
<one-to-many class="com.contego.arx.domain.Service"/>
</set>

And please use the [ code ] tags...

Everything looks right. I would suggest taking a look at how you implement hashCode() and equals(). You are using a Set for mapping that collection; problems with either of those overrides could cause an issue like that (especially hashCode()).

I am not overriding either of those methods.

It just seems really weird.

I suppose I will be forced to checkout the code and see if I can find the problem.
