Number format exception - not able to convert string to long value - angularjs

Question

JSP code --- I have used Angular js in scripting. The issue is that the form Data is not being sent to the resource method in portlet class. Also when I log the form data in console it displays empty. It takes up JSON data and append into form data. the json value is passed as transaction data { 1: "1", purchaseRegisterId: 33411, undefined: "book3.jpg" } and documentId is passed as documentId :: documents33411. these data is taken from the console log.
$scope.savePurchaseRegisterEntry=function(documentId, json){
console.log("documentId :: "+documentId);
//console.log("json");
console.log(json);
var fd = new FormData();
fd.append('auditDetailesId',$scope.auditDetailesId);
console.log(fd);
var documentcollection=[];
for(var key in json){
fd.append(key,json[key]);
if("purchaseRegisterId"!=key && key!=='undefined'){
documentcollection.push(key);
}
}
$.each( $("#"+documentId), function( input_key, input_value ) {
$.each( input_value.files, function( file_key, file_value ) {
fd.append('myFiles', file_value);
});
});
fd.append("documentCollectionIds",documentcollection.join(','));
console.log("fd");
console.log(fd);
console.log("documentcollectionids :: "+documentcollection.join(','))
//return false;
$http({
method:'POST',
url:'<%=savePurchaseRegisterEntry%>',
type:"json",
data:fd,
headers: {'Content-Type': undefined},
transformRequest:angular.identity
}).success(function(response){
console.log(response);
var response=angular.fromJson(response.selectedTransactionList);
$scope.dataList=angular.fromJson(response.data);
$scope.ariaValuenow =response.currentCount;
$scope.ariaValuemin=0;
$scope.ariaValueMax=response.data[0]['maxInputDocCount']* response.total;
$scope.percentageComplete=(($scope.ariaValuenow - $scope.ariaValuemin) * 100) / ($scope.ariaValueMax - $scope.ariaValuemin);
if($scope.percentageComplete==100){
$scope.saveStatus();
$scope.readyForAudit=true;
}else{
$scope.readyForAudit=false;
}
});
}
Resurces Method --- the data is being fetched here to store the values into database table.
public void savePurchaseRegisterEntry(ResourceRequest req,
ResourceResponse res) throws SystemException, IOException {
_log.info("i am in savePurchaseRegisterEntry!!!");
ThemeDisplay themeDisplay = (ThemeDisplay) req
.getAttribute(WebKeys.THEME_DISPLAY);
_log.info(" ----- " + ParamUtil.getString(req, "purchaseRegisterId"));
_log.info(" ----- " + ParamUtil.getLong(req, "purchaseRegisterId"));
String documentCollectionIds=ParamUtil.getString(req, "documentCollectionIds");
String[] documentCollectionIdArray=documentCollectionIds.split(",");
MultiDocumentUploadUtil.createFolder(req, themeDisplay ,ParamUtil.getLong(req, "purchaseRegisterId") , "purchaseRegisterId");
String fileIds=MultiDocumentUploadUtil.fileUpload(themeDisplay, req);
_log.info("fileIds : "+fileIds);
long purchaseRegisterId =ParamUtil.getLong(req, "purchaseRegisterId");
for(String s : documentCollectionIdArray){
System.out.println("s is "+Long.parseLong(s));
_log.info(Long.parseLong(s)+"long sssss "+ s+" s :: "+ParamUtil.getLong(req, s));
_log.info(Long.valueOf(s)+"long sssss "+ s+" s :: "+ParamUtil.getLong(req, s));
AuditDocumentCollection adc= AuditDocumentCollectionLocalServiceUtil.fetchByPurchaseRegisterIdAnddocumentCollectionId(purchaseRegisterId, Long.valueOf(s));
AuditDocumentCollection adc1=adc;
if(adc==null){
adc=AuditDocumentCollectionLocalServiceUtil.createAuditDocumentCollection(CounterLocalServiceUtil.increment());
}
adc.setDocumentCollectionId(Long.valueOf(s));
adc.setPurchaseRegisterId(purchaseRegisterId);
adc.setValue(ParamUtil.getLong(req, s));
if(adc1==null){
adc.setCreateDate(new Date());
adc.setCreatedBy(themeDisplay.getUserId());
adc.setModifiedBy(themeDisplay.getUserId());
adc.setModifiedDate(new Date());
AuditDocumentCollectionLocalServiceUtil.addAuditDocumentCollection(adc);
}else{
adc.setModifiedBy(themeDisplay.getUserId());
adc.setModifiedDate(new Date());
AuditDocumentCollectionLocalServiceUtil.updateAuditDocumentCollection(adc);
}
}
PurchaseRegister purchaseRegister=PurchaseRegisterLocalServiceUtil.fetchPurchaseRegister(purchaseRegisterId);
if(!fileIds.isEmpty()){
purchaseRegister.setDocumentIds(fileIds);
}
PurchaseRegisterLocalServiceUtil.updatePurchaseRegister(purchaseRegister);
JSONObject jsonobject = JSONFactoryUtil.createJSONObject();
long auditDetailesId=ParamUtil.getLong(req, "auditDetailesId");
jsonobject.put("selectedTransactionList",CommonUtil.getAuditProcessInfo( auditDetailesId));
PrintWriter out = res.getWriter();
out.write(jsonobject.toString());
out.flush();
out.close();
}
I suppose the data present in form data is being sent to resource method. it is not taking documentCollectionIds and its empty. The error I get is this,

Answer 1

check your file first the typscript file of your component if you give
it exactly the type Number, then your service
Or if it's through the html file of your component that you give it
the right type in parameter
For me it was in the html file that I gave him another type
different from number
