Incorrect VO instance updating.

Question

Hi all
I have a problem. I have a custom OAF page which contains a single context-dependent header record and an Advanced Table with the details associated with the header record. Between the header record and the detail record, there is another advanced table containing the various input columns required to create a detail record in the Advanced Table below.
Both the Input Table and the Detail Table utilise the same View Object, but each uses a different instance of the VO - let's call them VoDetailVO1 and VoDetailVO2 respectively.
There is a single select bean on the Advanced table which is used to Copy, Update and Delete the claim. The Copy and Update functions utilise the fairly standard method given in the Developers Guide which takes the values from the source row of the detail record ( VoDetailVO2 ) and copies them into the destination row of the input table's VO instance (VoDetailVO1 - initiliazed on initial page render).
Everything works fine up until the point where the values are inserted into the destination vo. At this point, instead of inserting into VoDetailVO1, the first row of VoDetailVO2 is being updated with the values.
Code synopsis here:
VoDetailsVOImpl sourceVO = getVoDetailsVO2();
VoDetailsVOImpl destVO = getVoDetailsVO1();
//no problems yet...
// get the source row..
Row sourceRow = sourceVO.getFirstFilteredRow("SelectRow", "Y");
// still no problems...
if (sourceRow != null)
for (int i = 0; i < attrCount; i++)
byte attrKind = attrDefs { i }.getAttributeKind();
// Bypass copying attributes internally created by BC4J or OA Framework.
// If you want to copy your own known dynamic attribute values from the
// source VO to the destination VO, then copy those attribute values
// explicitly using hardcoded attribute names.
if (!(attrKind == AttributeDef.ATTR_ASSOCIATED_ROW ||
attrKind == AttributeDef.ATTR_ASSOCIATED_ROWITERATOR ||
attrKind == AttributeDef.ATTR_DYNAMIC))
String attrName = attrDefs[ i ].getName();
// Loop through the attributes...
if (attrName == "TypeLookup"
|| attrName == "DateFrom"
|| attrName == "DateTo"
|| attrName == "AssignmentId"
|| attrName == "LineInput1"
// This all still works fine up to here. Now get a handle on the destination VO row..
VoDetailsVORowImpl destRow = destVO.first();
// There is only ever one row in this VO, so use of first() should be peachy;
destRow.setAttribute(attrName, attrVal);
// All gone wrong here - this updates the first row of the sourceVO as defined at the start of the procedure. (!!!)
else
// The user did not select a row
throw new OAException("PER", "MYCLAIM_NOROWSELECTED");
Anyone had any experience of this issue, or any idea on what's going wrong?

Hi,
When exactly you are creating and inserting record in destVO?
mere destVO.first() won't work, first() works if records are already fetched using query.
If I understand correctly, you should be creating new record in destVO (albait the only record) as follows:
Row row = destVO.createRow();
//defaulting logic should go here
row.setAttribute("Attr1", value);
destVO.insertRow(row);
row.setNewRowState(Row.STATUS_INITIALIZED);
