I have a WSO2 ESB-4.6.0 proxy that calls another proxy that calls an webservice.
Proxy1 --> Proxy2 --> Endpoint
If I directly call the second proxy via soapUI, the response is correctly returned and printed, but if I call the first proxy, then an blank body is returned.
In the ESB log, the outSequence of the Proxy1 is printed before the outSequence of the Proxy2.
Seems like the Send mediator present in the inSequence of the Proxy1 is making an asynchronous call to the Proxy2.
I've tried to replace the Send mediator by the Callout mediator, but the result is the same.
Follow this tutorial, but it didn't works also.
How to forward the response for the Proxy2 to the caller?
Please help. It's killing me!
EDIT
Problem solved! I was using a wrong port to specify the serviceURL parameter for Callout mediator.

The current proxies configuration:
Proxy1 (calling Proxy 2 - ManageWorkforce):
<proxy xmlns="http://ws.apache.org/ns/synapse" name="GetAppointmentSchedulePortalReqCS" transports="http https" startOnLoad="true" trace="disable">
<target>
<inSequence>
<xslt key="conf:ManageWorkforce/xslt/GetAppointmentSchedulePortalReqCS_Request.xsl"/>
<header name="Action" value="getAppointment"/>
<send>
<endpoint>
<address uri="https://localhost:9443/services/ManageWorkforce"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<xslt key="conf:ManageWorkforce/xslt/GetAppointmentSchedulePortalReqCS_Response.xsl"/>
<send/>
</outSequence>
<faultSequence/>
</target>
<publishWSDL key="conf:ManageWorkforce/GetAppointmentSchedulePortalReqCS.wsdl" />
</proxy>
Proxy 2 (calling Proxy3 -GetAppointmentPeopleProvCS):
<proxy xmlns="http://ws.apache.org/ns/synapse" name="ManageWorkforce" transports="https http" startOnLoad="true" trace="disable">
<target>
<inSequence>
<switch source="get-property('Action')">
<case regex="getAppointment">
<callout serviceURL="https://localhost:8243/services/GetAppointmentPeopleProvCS" action="getAppointment">
<source xmlns:s12="http://www.w3.org/2003/05/soap-envelope" xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/" xpath="s11:Body/child::*[fn:position()=1] | s12:Body/child::*[fn:position()=1]"/>
<target xmlns:s12="http://www.w3.org/2003/05/soap-envelope" xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/" xpath="s11:Body/child::*[fn:position()=1] | s12:Body/child::*[fn:position()=1]"/>
</callout>
</case>
<!-- another cases -->
<default/>
</switch>
<property name="RESPONSE" value="true" scope="default" type="STRING"/>
<header name="To" action="remove"/>
<send/>
</inSequence>
<outSequence>
<drop/>
</outSequence>
<faultSequence/>
</target>
<publishWSDL key="conf:ManageWorkforce/ManageWorkforce.wsdl"/>
</publishWSDL>
</proxy>
Proxy 3 (calling the service -GetAppointment):
<proxy xmlns="http://ws.apache.org/ns/synapse" name="GetAppointmentPeopleProvCS" transports="http https" serviceGroup="" startOnLoad="true" trace="disable">
<target>
<endpoint key="GetAppointment"/>
<inSequence>
<xslt key="conf:ManageWorkforce/xslt/GetAppointmentPeopleProvCS_Request.xsl"/>
</inSequence>
<outSequence>
<xslt key="conf:ManageWorkforce/xslt/GetAppointmentPeopleProvCS_Response.xsl"/>
<send/>
</outSequence>
<faultSequence/>
</target>
</proxy>
Final endpoint (service):
<endpoint xmlns="http://ws.apache.org/ns/synapse" name="GetAppointment">
<address uri="http://10.13.6.75:9764/services/GetAppointment" />
</endpoint>
