Question

我一直在追踪一些奇怪的行为，我终于设法隔离了它，我相信这是一个错误。为了重现这种行为，我创建了4个测试流程（在4个不同的mule文件中）：

<flow name="testhttpFlow">
    <http:listener config-ref="HTTP_Listener_AMIAB" path="/testsend" allowedMethods="GET, POST" doc:name="HTTP"/>
    <amqp:outbound-endpoint exchangeName="AMQP.DEFAULT.EXCHANGE" routingKey="masterMeep" exchangeType="direct" responseTimeout="10000" exchange-pattern="request-response" connector-ref="connector.amqp.mule.default" doc:name="AMQP-0-9"/>
</flow>

<flow name="testsendFlow" >
    <amqp:inbound-endpoint responseTimeout="10000" exchange-pattern="request-response" doc:name="AMQP-0-9" connector-ref="connector.amqp.mule.default" exchangeName="AMQP.DEFAULT.EXCHANGE" exchangeType="direct" queueDurable="true" queueName="masterMeep"/>
    <set-payload value="#[new java.util.ArrayList()]" doc:name="Set Payload to Collection"/>
    <scripting:component doc:name="JavaScript">
        <scripting:script engine="JavaScript"><![CDATA[payload.add("something1");
        payload.add("something2");
        result=payload;]]>
    </scripting:script>
    </scripting:component>
    <set-variable variableName="payloadCollection" value="#[payload]" doc:name="Set payloadCollection"/>
    <foreach doc:name="For Each">
        <choice doc:name="Choice">
            <when expression="payload == 'something1'">
                <amqp:outbound-endpoint exchangeName="AMQP.DEFAULT.EXCHANGE" routingKey="meep" exchangeType="direct" responseTimeout="60000" exchange-pattern="request-response" connector-ref="connector.amqp.mule.default" doc:name="AMQP-0-9 meep1"/>
            </when>
            <when expression="payload == 'something2'">

                var payloadCollection = message.getInvocationProperty('payloadCollection');
                var counter = message.getInvocationProperty('counter');
                payloadCollection.set(counter - 1, payload);
                result = payload;]]></scripting:script>
        </scripting:transformer>
    </foreach>
    <logger level="INFO" doc:name="Logger" message="#[payload]"/>
</flow>

</flow>

最初，没有testhttp流程。 testsend流程中的端点连接器是一个HTTP连接器，完美无缺。我立即在前面添加了额外的流，将HTTP连接器移动到该流，并添加了额外的请求 - 响应AMQP（因此等待内部AMQP请求 - 响应完成）内部AMQP请求 - 响应连接已停止工作

现在，他们只是挂起响应，直到超时发生，然后返回NullPayload。

这对我来说似乎不是正确的行为，感觉就像某种错误有两个＆＃34;层＆＃34; AMQP请求 - 响应一次进行。

有没有人让这种模式正常工作？

谢谢！
