Transfering Table data from one page to another page in OAF

Question

Hi All,
Could you please help me with the following requirement. I am trying to transfer the first page selected records to second page, but running into issue.
I have 2 custom OAF pages:
1st Page is Invoice Search page and upon searching for an invoice, user can select 'multi records' (its table region with multi-select) and click on upload button.
The button internally calls setForwardUrl method and calls 2nd page, where second page contains Advacned Table region to show the selected records from 1st page.
Since user can select more than 1 record in Search region on first page, I would like to hold all rows in an array of Hashmap with Integer index and transfer it to 2nd page. Following is the hashmap syntax I am using:
java.util.HashMap<Integer,InvoiceRow> map=new <Integer,InvoiceRow>(); // Here InvoiceRow is a custom CLASS structure with InvoiceNumber and Customer Number as variables inside.
But if I pass the above HashMap to setForwardURL method, the JDeveloper throwing an exception saying that "setForwardURL cannot invoke" message.
Could you please help me how can I transfer the first page multiselected records to second page?
Appreciate your time.

Venket, the approach i told you can try in below way:
public String getSelectedData()
        String whereclause = "(";
       // String whereclause1 = "(";
     XXCONTAINLINESVOImpl vo = this.getXXCONTAINLINESVO1();
      //OAViewObject vo=(OAViewObject)getXXDPECONTAINLINESVO1();
      // System.out.println("debTEST"+punload);
       Row[] sumVoRow =vo.getFilteredRows("Select1", "Y");
        System.out.println("deb multi select test"+sumVoRow.length);
    if (sumVoRow != null && sumVoRow.length > 0)
     for (int i = 0; i < sumVoRow.length; i++) {
              String wipEntityId =
              sumVoRow[i].getAttribute("LineId").toString();             
              whereclause = whereclause+sumVoRow[i].getAttribute("LineId").toString()+",";
            System.out.println("deb multi select test"+whereclause);
        if (whereclause.length() > 0 && whereclause.charAt(whereclause.length()-1)==',')
             StringBuilder b = new StringBuilder(whereclause);
             b.replace(whereclause.lastIndexOf(","), whereclause.lastIndexOf(",") + 1, ")" );
             whereclause = b.toString();
           //  return whereclause;          
        System.out.println("deb where clause test"+whereclause);
    return whereclause;
so this method will return the value as like : whereclause=(111,222,333) then put this in one session varibale and pass to the below method from CO
    public void processPOData (String wherclause)
        String query = getXXDPECONTAINDATAVO1().getQuery();//Old queryStringBuffer stringbuffer = new StringBuffer();
                  String newwhereclause ="LINE.LINE_ID IN "+wherclause;
                    System.out.println("DEB NEW where clause:"+newwhereclause);
                     StringBuffer stringbuffer = new StringBuffer();  
                   // stringbuffer.append("SELECT rownum LINE_NUM,A.* FROM (");
                    stringbuffer.append(query);
                    stringbuffer.append("  where ");
                   stringbuffer.append(newwhereclause);
                    ViewDefImpl viewdefimpl = getXXDPECONTAINDATAVO1().getViewDefinition();
                    viewdefimpl.setQuery(stringbuffer.toString());
                    System.out.println("DEB NEW QUERY TEST:"+stringbuffer.toString());
                    getXXDPECONTAINDATAVO1().executeQuery();
Let me know if stil r u facing isssue
