Add a new SubmitButton on a Page

Question

Hi,
I need to add a new submitButton on a page, so I have doen the following:
1) created a new stacklayout and submitbutton under it.
2) assigned the page's AM to this region.
3) assigned a new controller to this region.
4) using personalization added the region to the page.
However, when I press the button, I get an error :
My Controller code is :
public void processFormRequest(OAPageContext oapageContext, OAWebBean oawebBean)
super.processFormRequest(oapageContext, oawebBean);
if(oapageContext.getParameter("xxPrintReqButton") != null)
{    OAApplicationModule am = oapageContext.getApplicationModule(oawebBean);
MyReqsVOImpl vo = (MyReqsVOImpl) am.findViewObject("MyReqsVO");
OARow row = (OARow) vo.getFirstFilteredRow("select","Y");
String reqno = (String) row.getAttribute("RequisitionNumber");
// For testing only
OAMessageStyledTextBean fieldTest = (OAMessageStyledTextBean)oawebBean.findChildRecursive("PrintText");
fieldTest.setText(oapageContext,reqno );
My error stack is :
oracle.apps.fnd.framework.OAException: oracle.jbo.SQLStmtException: JBO-27122: SQL error during statement preparation. Statement: SELECT prh.requisition_header_id,

All I need to do is , when the button is processed , get the current row selected in the table using the single selection attribute and find the value of the attribute RequisitioNumber in that row. I plan to use this reqno as a parameter later. The table uses the VO MyReqsVO.
It appears the fwk is trying to bind the variables for the above VO and errors. Can i not simply refer to the VO instance which has already executed and displays the results in the advanced table ?
Any help is much appreciated.
Thanks
Shankar

Answer 1

Thanks Avaneesh.
how does fwk know which VO to use for am.findRowByref() ?
Currently I write in my PFR :
OAApplicationModule am = oapageContext.getApplicationModule(oawebBean);
String rowReference = oapageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
OARow row = (OARow) am.findRowByRef(rowReference);
String reqno = (String) row.getAttribute("RequisitionNumber");
throw new OAException(reqno,OAException.INFORMATION); --- to test only
but it gives Null Pointer exception on line
String reqno = (String) row.getAttribute("RequisitionNumber");
because i think it does not know which VO 's get method to use ?
Thanks
