URGENT - Data loss and query re-execution

Question

Is there a way to re-execute a VO and not lose data still not persisted to DB?
Or can I select and store rows not yet committed and, later, put it back on a VO instance, in a simple way?
This is needed to develop a wizard-type application, that persists data only at the end. The user must do a random number of searches and inserts on several tables, so I cannot see a way to insert row, requery data when needed and still mantain control. This is so easy with Hibernate, can't it be done with OAF?
Commit data before last step of operation is out of question.
Thanks for attention,
Elner Ribeiro.

Answer 1

Thanks so much for the response.
My VO is an EO basedVO, indeed. I don't need to mantain a specific current point in VO, but when I re-query it (VO) I'm losing all data not saved.
Is there anything wrong with my approach?
Thanks for your attention.

The method with problem (called from a link in a table, one link for line [solicitant]):
public void initTelaOutrasInfo(MtsRtOtherInformationsAllVOImpl oivo, MtsRtSolicitantsAllVOImpl svo, MtsRtCardMilesAllVOImpl cvo, MtsRtVaccinesAllVOImpl vvo, OADBTransaction txn, String rowReference) {
          MtsRtSolicitantsAllVORowImpl sRow = (MtsRtSolicitantsAllVORowImpl) findRowByRef(rowReference);
if (sRow == null) {
throw new OAException("Error [Method: initTelaOutrasInfo]");
svo.setCurrentRow(sRow);
     oivo.initQuery(sRow.getDocumentNumber());
MtsRtOtherInformationsAllVORowImpl oRow = (MtsRtOtherInformationsAllVORowImpl) oivo.first();
if (oRow == null) {
//Not found on DB, creates a new one
oivo.setMaxFetchSize(0);
oivo.executeQuery();
oRow = (MtsRtOtherInformationsAllVORowImpl) oivo.createRow();
oivo.insertRow(oRow);
oRow.setDocumentNumber(sRow.getDocumentNumber());
oRow.setOrgId(sRow.getOrgId());
oRow.setOtherInfoId(sRow.getRequisitionId());
oracle.jbo.domain.Number seq = txn.getSequenceValue("MTS_RT_OTHER_INFORMAT_ALL_S");
oRow.setOtherInfoId(seq);
oRow.setNewRowState(Row.STATUS_INITIALIZED);
oivo.setCurrentRow(oRow);
cvo.initQuery(oRow.getOtherInfoId());
vvo.initQuery(oRow.getOtherInfoId());
createNovoCartao(oivo, cvo); //Creates a new MtsRtCardMilesAllVORowImpl
createNovaVacina(oivo, vvo); //Creates a new MtsRtVaccinesAllVORowImpl
} else {
//Found on DB, queries children
cvo.setMaxFetchSize(200);
vvo.setMaxFetchSize(200);
cvo.initQuery(oRow.getOtherInfoId());
vvo.initQuery(oRow.getOtherInfoId());
