Creating VO Dynamically and Copying Attributes

Question

Hi anyone,
I've developed a SimpleSearch with LOVs that result in a multi-selection list.
Once the rows are selected, I want to carry them over and display on the next page.
I'm trying to keep it very simple, using OAFramework wizards an such but I'm struggling to get this accomplished, mostly due to lack of JAVA experience.
I was trying to follow the advice from "How to show selected rows only in tablebean" but I don't know how to create a VO dynamically and am new to JAVA (which is why I tried to keep it simple).
What I need help with desperately is:
1) The correct syntax/code for creating a simple VO dynamically - examples in the OA Dev guide are hard to follow.
2) Correct syntax/code for copying attributes using setAttribute().
3) Does this new VO appear under the BC4J Components directory? If not, how do I attach it to the table's columns?
4) Anything else I should include or watch out for?
Thanks very much.

Hi Ramkumar,
I did create a VO declaratively before but am stuck on syntax again in the AMImpl.
I'm getting the error: oracle.jbo.TooManyObjectsException: JBO-25013: Too many objects match the primary key oracle.jbo.Key[10006 ].
Could you look at my code and see what is missing?
public void SelectItemInstance( )
CustibSummaryVOImpl vo = getCustibSummaryVO1();
CustibChangeVOImpl dvo = getCustibChangeVO1();
Row[] sourceRows = vo.getFilteredRows("SelectFlag", "Y");
// getFilteredRows returns a zero-length array if it finds no matches.
if (sourceRows != null && sourceRows.length > 0)
int numRows = sourceRows.length;
for (int i = 0; i < numRows; i++)
// For every row with a selected checkbox, we want call
// the create( ) and insert()wrapper.
Row newRow = dvo.createRow();
newRow.setAttribute("ItemInstance", sourceRows.getAttribute("ItemInstance"));
newRow.setAttribute("Item",sourceRows[i].getAttribute("Item"));
newRow.setAttribute("TagNumber",sourceRows[i].getAttribute("TagNumber"));
newRow.setAttribute("Client",sourceRows[i].getAttribute("Client"));
newRow.setAttribute("Resp",sourceRows[i].getAttribute("Resp"));
newRow.setAttribute("Service",sourceRows[i].getAttribute("Service"));
newRow.setAttribute("Project",sourceRows[i].getAttribute("Project"));
newRow.setAttribute("TCAAccount",sourceRows[i].getAttribute("TCAAccount"));
newRow.setAttribute("OrderId",sourceRows[i].getAttribute("OrderId"));
newRow.setAttribute("PartyId",sourceRows[i].getAttribute("PartyId"));
newRow.setAttribute("AccountId",sourceRows[i].getAttribute("AccountId"));
dvo.insertRow(newRow);
} // end selectItemInstance()
Thanks ever so much.
