[RESOLVIDO] Problema com Flex e SOAP: Fault lançada quando string de retorno ultrapassa tamanho espe

Olá pessoal. Sou novo em Flex e SOAP, então desculpem se a pergunta parecer óbvia demais.

Estou com um problema estranho. Tenho uma aplicação em Flex que consome um webservice, e tudo funciona muito bem até eu tentar retornar uma string maior que 490 caracteres, o que acho bastante estranho. Em meus testes, se eu tentar retornar uma string de 491 caracteres, recebo a seguinte mensagem:

SOAP Response cannot be decoded. Raw response: faultCode="DecodingError" faultDetail="null"

Fiz um cliente PHP, só pra testar, que consome o mesmo webservice, e chama a mesma operação. Mas no caso desse outro cliente, não tenho nenhum erro e a string é retornada completa, sem problema algum.,

Aqui está meu script:

?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 

               xmlns:s="library://ns.adobe.com/flex/spark" 

               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">



    <fx:Script>

        <![CDATA[

            import mx.collections.ArrayCollection;

            import mx.rpc.events.ResultEvent;

            

            [Bindable]private var testValue:String;

            

            protected function floappService_variableTestResultHandler(event:ResultEvent):void

            {

                this.testValue = event.result as String;

            }

            

        ]]>

    </fx:Script>



    

    

    <fx:Declarations>

        <s:WebService id="ws"

                      wsdl="mywebservice?wsdl"
>

            

            <s:operation name="variableTest" 

                         result="floappService_variableTestResultHandler(event)"

                         fault="mx.controls.Alert.show(event.fault.faultString)"/>

            

        </s:WebService>

    </fx:Declarations>

    

    <mx:VBox width="100%" height="100%">

        

        

        <mx:Form width="100%" height="100%">


            <mx:FormItem>

                <mx:HBox>

                    <s:Button label="Variable Test" click="ws.variableTest()"/>

                    <mx:Text text="{testValue}"/>

                </mx:HBox>

            </mx:FormItem>

            

        </mx:Form>

    </mx:VBox>

</s:Application>

Aqui a resposta que recebo, sem faltas (string com 490 'A's)

E aqui o caso quando acontece o problema (string com 491 'A's):

</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Chequei os dois XMLs no XML Validator da W3 (http://www.w3schools.com/XML/xml_validator.asp), e não tive erros

A única diferença entre as duas respostas é o Content-Length, então acho que o problema está por aí (mas não sei o quê/por que)

Obrigado por qualquer ajuda que seja possível!
