Simple WSOESB Proxy doen't response - wso2-esb

Question

Very simple example. Request:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header/>
<soapenv:Body>
<T>
<m1>bysy</m1>
<m1>momo</m1>
<m1>gigi</m1>
</T>
</soapenv:Body>
</soapenv:Envelope>
I want to iterate and log every element in tag m1.
Proxy code:
<proxy xmlns="http://ws.apache.org/ns/synapse" name="Loopback" transports="https,http"
<target>
<inSequence>
<property name="OUT_ONLY" value="true" scope="axis2"/>
<iterate expression="//T/m1">
<target>
<sequence>
<property name="OUT_ONLY" value="true" scope="axis2"/>
<log level="custom">
<property name="M1" expression="//text()"/>
</log>
<drop/>
</sequence>
</target>
</iterate>
</inSequence>
</target>
</proxy>
It work as expected and logs all values. But WSO2ESB server doesn't close connection, until it falls with timeout. (I use SOAPUI for testing)
I tried to put properties OUT_ONLY RESPOND NO_KEEPALIVE in different part of proxy but it didn't help, as well I tried to use , with same result.
It looks like problem in iterate mediator which doesn't let to inSequence to terminate and send response to client. Once i remove it, proxy disconnect immediately with status code '202' message accepted.

Answer 1

This is because, by default, attribute "continueParent" is set to false with iterate mediator : change to <iterate continueParent="true" expression="//T/m1">
And you should explicitly send a 202 inside your inSequence, set this property : <property name="FORCE_SC_ACCEPTED" value="true" scope="axis2"/>
