Re: [Hibernate] Failure to lazily initialize a collection

Here's the mapping I'm using for the set:

   <set role="referenceSequences" table="ReferenceSequenceGeneAssoc" 
lazy="true" cascade="all">
     <key column="geneId" type="string" />
     <many-to-many column="referenceSequenceId" 
class="org.pharmgen.db.DbReferenceSequence" />
   </set>


And if I change it to lazy="false," I get:

With the 1.1.4b build I get:

BTW, all this works with 1.3!
