Hibernate 2.1.1
Oracle 8.1.6

Here is my snippets.

mapping document:

Code:

<many-to-one
          name="cargo"   
          class="eg.CodeCargo">
   <column name="CARGO"/>
</many-to-one>

    <many-to-one
        name="cargoWaggon"
        class="eg.CargoWaggon"
      >
        <column name="NUM_TRAIN" />
        <column name="WAG_NUM" />
        <column name="DATE_INP" />
    </many-to-one>
...


Everithing works fine, until one of composite-id column is NULL
then UnresolvableObjectException occurs
here is part of stack trace:

Code:
2004-05-27 09:24:36,408 ERROR [STDERR] net.sf.hibernate.UnresolvableObjectException: No row with the given identifier exists: com.azovstal.ugdt.hibernate.CargoWaggonPK@10704e1[numTrain=<null>,numWaggon=108,dateInp=<null>], of class: com.azovstal.ugdt.hibernate.CargoWaggon
   at net.sf.hibernate.UnresolvableObjectException.throwIfNull(UnresolvableObjectException.java:38)
   at net.sf.hibernate.impl.SessionImpl.internalLoad(SessionImpl.java:1881)
   at net.sf.hibernate.type.ManyToOneType.resolveIdentifier(ManyToOneType.java:68)

   at net.sf.hibernate.impl.SessionImpl.find(SessionImpl.java:3440)
   at net.sf.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:177)



almost the same occurs, if eg.CodeCargo has value which is absent in referenced table

Code:
2004-05-27 09:34:54,006 ERROR [STDERR] net.sf.hibernate.UnresolvableObjectException: No row with the given identifier exists: 117001, of class: com.azovstal.ugdt.hibernate.CodeCargo

   at net.sf.hibernate.impl.SessionImpl.find(SessionImpl.java:3440)
   at net.sf.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:177)



I do understand why its happening, what am I should write to avoid it?

which ones?
Persistent objects were generated with hbm2java

Code:
      Transaction tx = session.beginTransaction();
      Criteria criteria = session.createCriteria(template.getClass());

      criteria.add(Expression.ge("dateWeight", beginDate));
      criteria.add(Expression.le("dateWeight", endDate));

      criteria.setMaxResults(maxresults);
      retVal = criteria.list();
   
      tx.commit();

You have an exception because with your parameter, you don't have result so the List result is null.
Show your mapping files and the java sources with the criteria... not the POJO.
