Submitting a form from a javascript method gives javax.faces.el.EvaluationException

[satya anvesh]

Hi All

I need to validate a form through JavaScript method and then the form should be submitted. I've tried to do this other similar ways, but I encounter a javascript error.
So finally I'm convinced with the JavaScript methods which validates and does a call to the script in the other server. But the problem is when I'm submitting the form from JavaScript method, I get a

javax.faces.el.EvaluationException: Cannot get value for expression '#{bidBuyProcessor.paymentMethodFees}'

Please help me...!!!
Below is the my code:

buy.jsp:

 function imola_buy()
{
	if(validateImolaBuy())
  {
	  subFormImola('${bidBuyProcessor.user.currentOrganizationId}','${bidBuyProcessor.vehicleDetails.currentAuction.id}', '2');
  }
	return false;
}

function validateImolaBuy()
{
  var atcTransportOptions  = document.getElementsByName('buyNowForm:subviewVehicleSummaryPaymentMethods:atcTransportOption');
  var buyerTransportOptions = document.getElementsByName('buyNowForm:subviewVehicleSummaryPaymentMethods:buyerTransportOption');
  var paymentMethods = document.getElementsByName('buyNowForm:subviewVehicleSummaryPaymentMethods:paymentMethod');
  
	 if(getRadioButtonValue(atcTransportOptions) == undefined && getRadioButtonValue(buyerTransportOptions) == undefined)
	 {
      alert('Please select a transport option');
      return false;
	 }   
	 else if(getRadioButtonValue(paymentMethods) == undefined)
	 {
		  alert('Please select a payment method');
	    return false;
	 }
	 else   
      return true;	
}

<h:form id="buyNowForm" onsubmit="return imola_buy();">

<h:commandLink id="buyNow" styleClass="buttonLabel" action="#{bidBuyProcessor.buy}">
							<h:outputText value="Buy Now"/>
		            	</h:commandLink>
</h:form>
 

buy.js:

function subFormImola(loginOrgId, auctionId, buyPriceOptionId)
{
  LOGIN_ORGANIZATION_ID = loginOrgId;
  AUCTION_ID = auctionId;
  BUY_PRICE_OPTION_ID = buyPriceOptionId;

  if (! bidBuyAPIConnectionEstablished())
  {
    return false;
  }
  
  submitBuy();
  
}

function submitBuy()
{
	getBuyContext();
	
	buyContext.setPaymentMethodId(getRadioButtonValue(document.getElementsByName('buyNowForm:subviewVehicleSummaryPaymentMethods:paymentMethod')));
	
	buyContext.submitBuyNow('buyResultCallback');
}

function buyResultCallback(status)
{
  if(status == LOGIN_SUCCESS)
  {
	errorHappened = false;  
	document.buyNowForm.submit();
  }
  else 
  {
	window.alert("There was an error processing your request. Status code: "+status);
	errorHappened = true;  
  }
}
  

Thanks in advance...

first: Your supposed to use a validator each in a backing bean method to colect data for each UIInput object.
You do not use javascript it devoids the point.
