Mule - http.status를 기반으로 메시지를 라우팅 할 수 없음

Question

Mule 응용 프로그램에서 HTTP 아웃 바운드 종점에서받은 응답 코드를 기반으로 선택 라우터를 만들려고합니다. 내 설정은 다음과 같습니다 - 나는 this previous question에서 제공하는 답변 다음 :

******************************************************************************** 
Message    : Execution of the expression "message.inboundProperties['http.status']] == 20" failed. (org.mule.api.expression.ExpressionRuntimeException). Message payload is of type: ReleasingInputStream

http.status 인바운드 속성은 출력과 범위에 분명히 : 나는 다음과 같은 오류가, 그러나

<set-variable variableName="http.disable.status.code.exception.check" value="true" doc:name="Variable"/> 
<http:outbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" path="hello" contentType="text/xml" method="POST" doc:name="HTTP"/> 

<logger level="INFO" doc:name="Logger"/> 

<choice doc:name="Choice"> 
    <when expression="#[message.inboundProperties['http.status']] == 200"> 
     <logger level="DEBUG" message="HTTP SUCCESS" doc:name="Debug"/> 
    </when> 
    <otherwise> 
     <logger level="DEBUG" message="HTTP FAILURE" doc:name="Debug"/>     
    </otherwise> 
</choice> 

을 선택 라우터 바로 앞에있는 내 로거의 내용은 다음과 같습니다.

왜이 문제가 발생하는지 파악할 수 있습니까? 미리 감사드립니다.

당신과 같이 노새 표현 괄호 안에 운영자를 배치해야합니다 :

<when expression="#[message.inboundProperties['http.status'] == '200']">
