I’m building a small application for myself. It will manage my orders and invoices. Reason I’m doing this is mainly to try out new stuff. I thought I’ld try out a Grails soap backend with a Flex frontend. Doesn’t sound to difficult, right? Well I ran into a problem and it took me some time before I found a solution.<\/p>\n
I had created a simple webservice that would return all my orders. Something like this piece of code<\/p>\n
class PurchaseOrderWebService {<\/p>\n
boolean transactional = true
\nstatic expose=[‘xfire’]<\/p>\nPurchaseOrder findById(Long id){
\nreturn PurchaseOrder.get(id)
\n}<\/p>\nPurchaseOrder[] findAll(){
\nprintln(‘listing all’)
\nreturn PurchaseOrder.list() as PurchaseOrder[]
\n}<\/p>\nPurchaseOrder save(PurchaseOrder order){
\nreturn order.save()
\n}
\n}<\/p><\/blockquote>\nPretty simple don’t ya think. This is now accessable as a soap webservice. In Flex I used the generator to generate all my stubs. The Flex code would look something like this<\/p>\n
public function loadData():void
\n{
\nAlert.show(“test5”);
\nvar service:generated.webservices.PurchaseOrderWeb = new generated.webservices.PurchaseOrderWeb();
\nservice.addEventListener(FaultEvent.FAULT,errorHandler);
\nservice.addfindAllEventListener(findAllListener);
\nservice.findAll();
\n}<\/p>\npublic function findAllListener(e:generated.webservices.FindAllResultEvent):void
\n{
\nthis.orderDG.dataProvider = e.result;
\n}<\/p><\/blockquote>\nHere I show the alert so I’m sure I’m not using a cached version of the SWF. However doing this returns a Error #2032. Why? Well I don’t know. I tried using the soap service from another programming language (c#) and it worked fine. After much googling I finally found the answer. For some reason Flex doesn’t like it when you don’t supply an argument to the soap call. The piece of code that finally did the trick looks like this<\/p>\n
Grails<\/p>\n
class PurchaseOrderWebService {<\/p>\n
boolean transactional = true
\nstatic expose=[‘xfire’]<\/p>\nPurchaseOrder findById(Long id){
\nreturn PurchaseOrder.get(id)
\n}<\/p>\nPurchaseOrder[] findAll(String dummy){
\nprintln(‘listing all’)
\nreturn PurchaseOrder.list() as PurchaseOrder[]
\n}<\/p>\nPurchaseOrder save(PurchaseOrder order){
\nreturn order.save()
\n}<\/p>\n}<\/p><\/blockquote>\n
Flex<\/p>\n
public function loadData():void
\n{
\nAlert.show(“test6”);
\nvar service:generated.webservices.PurchaseOrderWeb = new generated.webservices.PurchaseOrderWeb();
\nservice.addEventListener(FaultEvent.FAULT,errorHandler);
\nservice.addfindAllEventListener(findAllListener);
\nservice.findAll(“test”);
\n}<\/p>\npublic function findAllListener(e:generated.webservices.FindAllResultEvent):void
\n{
\nthis.orderDG.dataProvider = e.result;
\n}<\/p><\/blockquote>\nStrange bug if you ask me. I hope this get’s indexed and it will help other people facing this problem.<\/p>\n","protected":false},"excerpt":{"rendered":"
