Recalculate button in AdvanceTable

Question

Hi,
I have a advance table and the Recalculate button. The issue is below.
I have a row with few LOV's and Percent, Quantity and Amount columns. The Percent, Quantity and Amount are transient variables.
If I enter a value in Percent field, it fires the event update and calculates the Quantity and Amount values. If I add a new row, the 1st row Percent, Quantity and Amount are calculated and displayed in the Totals. After a I enter the values in 2nd row and click the button Recalculate, it is going in to the update if condition written for Percent FireAction and is erroring. what needs to be done to do the Recalculate button.
Thanks,
HC

Hi Gyan,
When I click the recalculate button, the process is going to the if loop written for the Percentage update.
Please see the below code. The error is at line "int v_percent = Integer.parseInt(pRow.getAttribute("DisplayPercent").toString());"
The error message is "oracle.apps.fnd.framework.OAException: java.lang.NullPointerException". I guess the pRow might be null. The below update was written as the event for Percentage to update Amount and Quantity in the row.
if ("update".equals(s))
//Use this code to get the row refernce of the clicked row.
String rowRf = pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
pageContext.writeDiagnostics(this,"rowRf: "+rowRf,1);
// Serializable[] parameters1 = { rowRf };
OAApplicationModule am3 = (OAApplicationModule)pageContext.getApplicationModule(webBean);
OAApplicationModule rootAM1 = pageContext.getRootApplicationModule();
PoRequisitionLinesVOImpl prl1 = (PoRequisitionLinesVOImpl)rootAM1.findViewObject("PoRequisitionLinesVO");
PoRequisitionLinesVORowImpl prlr1 = (PoRequisitionLinesVORowImpl)prl1.getCurrentRow();
pageContext.writeDiagnostics(this,"DisplayTxnAmount: "+prlr1.getDisplayTxnAmount(),1);
int v_amount = Integer.parseInt(prlr1.getDisplayTxnAmount().toString());
pageContext.writeDiagnostics(this,"v_amount: "+v_amount,1);
int v_quantity = Integer.parseInt(prlr1.getQuantity().toString());
pageContext.writeDiagnostics(this,"v_quantity: "+v_quantity,1);
Row pRow = (Row)am3.findRowByRef(rowRf);
pageContext.writeDiagnostics(this,"pRow: "+pRow,1);
int v_percent = Integer.parseInt(pRow.getAttribute("DisplayPercent").toString());
pageContext.writeDiagnostics(this,"v_percent: "+v_percent,1);
int v_DisplayQuantity = v_percent * v_quantity/100;
int v_DisplayAmount = v_percent * v_amount/100;
pageContext.writeDiagnostics(this,"v_DisplayQuantity: "+v_DisplayQuantity,1);
pageContext.writeDiagnostics(this,"v_DisplayAmount: "+v_DisplayAmount,1);
pRow.setAttribute("DisplayQuantity", Integer.toString(v_DisplayQuantity));
pRow.setAttribute("DisplayAmount", Integer.toString(v_DisplayAmount));
pageContext.writeDiagnostics(this,"Before calling handlePercentChangeEvent: "+rowRf,1);
//am3.invokeMethod("handlePercentChangeEvent", parameters1);
}
