Help With Error in Code Generated by WSDL Wizard

Question

I generated code using the webservice wizard, and then wrote
a simple mxml file to test the code. I get this error:
1061: Call to a possibly undefined method getClass through a
reference with static type Class.
It occurs in the following code:
* Internal event handler to process a successful operation
call from the server
* The result is decoded using the schema and operation
settings and then the
* events get passed on to the actual facade that the user
employs in the application
* @private
private function
processResult(result:Object,wrappedData:Object):void
var token:AsyncToken = wrappedData.returnToken;
var currentOperation:WSDLOperation = wrappedData.operation;
var decoder:SOAPDecoder = new SOAPDecoder();
decoder.resultFormat="object";
decoder.ignoreWhitespace = true;
decoder.makeObjectsBindable=true;
decoder.wsdlOperation = currentOperation;
decoder.schemaManager = currentOperation.schemaManager;
var body:Object = result.message.body;
var stringResult:String = String(body);
if (stringResult == null || stringResult == "")
return;
var soapResult:SOAPResult =
decoder.decodeResponse(result.message.body);
if (soapResult.isFault)
var faults:Array = soapResult.result as Array;
for each (var soapFault:Fault in faults)
var soapFaultEvent:FaultEvent =
FaultEvent.createEvent(soapFault,token,null);
token.dispatchEvent(soapFaultEvent);
} else {
result = decoder.decodeResponse(result.message.body).result;
if (result is ArrayCollection)
//shoud upcast to specific type here
var arrayTypedClass:Class =
SchemaTypeRegistry.getClass(currentOperation.outputMessage.parts[0].type);
result = new arrayTypedClass(result.source);
var event:ResultEvent =
ResultEvent.createEvent(result,token,null);
token.dispatchEvent(event);
The statement where the error occurs is in
bold above. The comment above that line says I should upcast
to a specific type here, but I don't know what that means. Which
specific type? How do I determine what type to upcast to?
Any help would be appreciated.
TIA,
Randy

Hi Martin,
From the error you showed it seems you have upgraded your SDK
version, but not the builder. The problem you are experiencing
comes from the fact that the one of the SDK classes (the
SchemaTypeRegistry) has been updated from a static to a dynamic
class. Therefore, using the getClass() call on it will not work any
more. Also, the lines that register type mappings won't work.
We've updated the generated code, but it seems you are
running on an older version. Now, to fix your code you have to:
1. Locate all occurences where the SchemaTypeRegistry class
is called as a static class.
2. Replace the SchemaTypeRegistry part from the method calls
with SchemaTypeRegistry.getInstance(), like this:
SchemaTypeRegistry.registerClass(params) becomes
SchemaTypeRegistry.getInstance().registerClass(params)
The problem is that when you re-generate the code you will
have to re-do all these changes again.
Hope this helps,
Cristian
