Hi Thomas,

Thanks a lot, just tried this, worked like a charm.
BTW, Criteria object returned by criteria.clone() gets affected if the
original criteria object is modified. Is this a bug?
For examples, if I have an existing criteria, then I do:
Criteria criteriaClone = criteria.clone();
criteria.getSelectColumns().clean();

both criteria and criteriaClone have empty selectcolumn list.
Thanks,


David
