PersistentGenericMap doesn't really apply "not-found"
-----------------------------------------------------

         Key: NH-836
         URL: http://jira.nhibernate.org/browse/NH-836
     Project: NHibernate
        Type: Bug
    Versions: 1.2.0.Beta2    
    Reporter: Jerry Haltom
    Priority: Trivial



        <map
            name="InputItems"
            lazy="true"
            table="MemberInputItem">
            <key
                column="MemberId" />
            <index-many-to-many
                column="MemberInputId"
                class="ISIS.Data.Core.MemberInput, ISIS.Data" />
            <one-to-many
                not-found="ignore"
                class="ISIS.Data.Core.MemberInputItem, ISIS.Data" />
        </map>


Though "not-found" is set to ignore on the one-to-many, it's meaning is a bit unclear. It doesn't actually prevent the indexer of the PersistentGenericMap from throwing an exception. I'm unsure of the intended purpose. Dictionaries now provide a TryGetValue which can be used by code which doesn't want an exception to be thrown in this circumstance. Should this not be the recommended way users of hte dictionary expect no results?
