Need to add Run time Validation in Advanced table column

Question

Hi Friends,
I've an requirement to add the validation in Advanced table.
issue is, In eAM Work Order, currently we have ability to add Operation Seq Number as 0, but we need to add one validation to avoid 0 value.
Oracle gave us the patch but we cannot apply the patch which is bring up the eAM version to higher level.
decided to handle it in controller and made changes to the handleOpSummaryEvent event.
Below is my code.
if("handleOpSummaryEvent".equals(s))
OAApplicationModule oaapplicationmodule = oapagecontext.getApplicationModule(oawebbean);
String wipEntityID = ((Number)oapagecontext.getTransactionValue("WipEntityId")).toString();
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside wip entity Id: ").append(wipEntityID).toString(), 2);
String opSeqTrans = (String)oapagecontext.getTransactionValue("SelectedOpSeq");
String op = oapagecontext.getParameter("OpSeqSummary");
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside op : ").append(op).toString(), 2);
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside operation Seq Value: ").append(opSeqTrans).toString(), 2);
ViewObject vo = oaapplicationmodule.findViewObject("OperationSummaryVO");
if (!vo.equals(null))
oapagecontext.writeDiagnostics(this, "Inside vo not equals to null", 2);
vo.setWhereClauseParam(0,wipEntityID);
vo.executeQuery();
int fetchedRowCount = vo.getRowCount();
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside fetched row count : ").append(fetchedRowCount).toString(), 2);
if(fetchedRowCount > 0)
RowSetIterator iter = vo.findRowSetIterator("opIter");
if(iter == null)
iter = vo.createRowSetIterator("opIter");
iter.setRangeStart(0);
iter.setRangeSize(fetchedRowCount);
Row row = null;
for(int i = 0; i < fetchedRowCount; i++)
OperationSummaryVORowImpl operationsummaryvorowimpl = (OperationSummaryVORowImpl)iter.getRowAtRangeIndex(i);
Number opSeq = operationsummaryvorowimpl.getOperationSeqNum();
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside operation Seq Value 2: ").append(opSeq.intValue()).toString(), 2);
float f = 0.0F;
if(opSeq != null)
f = opSeq.floatValue();
if(f <= 0.0F)
//throw new OAException("Enter Valid Operation Sequence Number. 0 is Invalid Operation Sequence",OAException.ERROR);
oapagecontext.writeDiagnostics(this, "Inside opseq equals 0", 2);
iter.closeRowSetIterator();
String s2 = oapagecontext.getParameter("evtSrcRowRef");
Serializable aserializable[] = {s2, "Summary"};
oaapplicationmodule.invokeMethod("handleOpEvent", aserializable);
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside s2 : ").append(s2).toString(), 2);
Issue is, when ever i create new line and enter any value at operation seq, validation fires and new line is deleted.
Please let me know how i can fix this issue.
Thanks

Hi Friends,
I solved it by myself.
if("handleOpSummaryEvent".equals(s))
OAApplicationModule oaapplicationmodule = pageContext.getApplicationModule(webBean);
String s2 = pageContext.getParameter("evtSrcRowRef");
OperationSummaryVORowImpl rowimpl = (OperationSummaryVORowImpl)oaapplicationmodule.findRowByRef(s2);
Number opSeq = ((OperationSummaryVORowImpl)(rowimpl)).getOperationSeqNum();
pageContext.writeDiagnostics(this, (new StringBuilder()).append("Inside row operation sequence: ").append(opSeq.intValue()).toString(), 2);
if (opSeq.intValue() == 0)
throw new OAException("Enter Valid Operation Sequence Number. 0 is Invalid Operation Sequence",OAException.ERROR);
Serializable aserializable[] = {s2, "Summary"};
oaapplicationmodule.invokeMethod("handleOpEvent", aserializable);
Thanks
