WSO2 ESB iterate mediator joining - iterator

Question

i'm facing some problems with this process.. let me explain:
i want to call two services and join the responses in this order:
i have the first service's response:
<locations xmlns="http://ssocial.com/traceit/services/location">
<location>
<latitude>-33.45209980</latitude>
<longitude>-70.66241990</longitude>
<altitude>0.0</altitude>
<creation>2016-09-04T14:59:48.000-03:00</creation>
<updated>2016-09-04T14:59:48.000-03:00</updated>
<deviceId>25</deviceId>
</location>
<location>
<latitude>-33.45149521</latitude>
<longitude>-70.66146224</longitude>
<altitude>817.0</altitude>
<creation>2016-09-04T13:18:43.000-03:00</creation>
<updated>2016-09-04T13:18:43.000-03:00</updated>
<deviceId>25</deviceId>
</location>
</locations>
then i have the secon service's response :
<device xmlns="http://ssocial.com/traceit/services/device">
<id>25</id>
<code>mobile_02</code>
<type>
<id>1</id>
<name>MOBILE</name>
</type>
And then, the final response that i would like to have is :
<locations xmlns="http://ssocial.com/traceit/services/location">
<location>
<latitude>-33.45209980</latitude>
<longitude>-70.66241990</longitude>
<altitude>0.0</altitude>
<creation>2016-09-04T14:59:48.000-03:00</creation>
<updated>2016-09-04T14:59:48.000-03:00</updated>
<deviceId>25</deviceId>
<device xmlns="http://ssocial.com/traceit/services/device">
<id>25</id>
<code>mobile_02</code>
<type>
<id>1</id>
<name>MOBILE</name>
</type>
</device>
</location>
<location>
<latitude>-33.45149521</latitude>
<longitude>-70.66146224</longitude>
<altitude>817.0</altitude>
<creation>2016-09-04T13:18:43.000-03:00</creation>
<updated>2016-09-04T13:18:43.000-03:00</updated>
<deviceId>25</deviceId>
<device xmlns="http://ssocial.com/traceit/services/device">
<id>25</id>
<code>mobile_02</code>
<type>
<id>1</id>
<name>MOBILE</name>
</type>
</device>
</location>
</locations>
i'm really having lot of troubles trying to join both responses like that, and this is my sequence in wso2:
<sequence name="getDeviceInfoByLocationProcess" trace="disable" xmlns="http://ws.apache.org/ns/synapse">
<property expression="count(//ns1:locations/ns1:location)" name="LOCATIONS_COUNT" scope="default" type="STRING" xmlns:ns1="http://ssocial.com/traceit/services/location"/>
<iterate description="" expression="//ns1:locations/ns1:location/ns1:deviceId" id="LOCATIONS_ITERATOR" xmlns:ns1="http://ssocial.com/traceit/services/location">
<target>
<sequence>
<property description="device_id" expression="//ns1:deviceId" name="device_id" scope="default" type="STRING"/>
<sequence key="getDeviceInfoProcess"/>
</sequence>
</target>
</iterate>
<log level="custom">
<property expression="//ns1:locations" name="LOCATIONS" xmlns:ns1="http://ssocial.com/traceit/services/location"/>
<property expression="//ns2:device" name="DEVICE_INFO" xmlns:ns2="http://ssocial.com/traceit/services/device"/>
</log>
<property name="ECNCLOSING_ELEMENT" scope="default">
<wrapper xmlns=""/>
</property>
<aggregate id="AGG_01">
<completeCondition>
<messageCount max="-1" min="{get-property('LOCATIONS_COUNT')}"/>
</completeCondition>
<onComplete expression="//ns2:device" xmlns:ns2="http://ssocial.com/traceit/services/device">
<log level="full">
<property expression="$ctx:LOCATIONS_COUNT" name="COUNTER"/>
<property expression="$ctx:ECNCLOSING_ELEMENT" name="ENCLOSING"/>
</log>
<call/>
</onComplete>
</aggregate>
and actually with this sequence, i'm just getting this:
<device xmlns="http://ssocial.com/traceit/services/device">
<id>25</id>
<code>mobile_02</code>
<type>
<id>1</id>
<name>MOBILE</name>
</type>
In advance , thank you very much for the help

Answer 1

I can't see the content of "getDeviceInfoProcess" sequence, but I guess your are using call mediator. So, as a result of those requests (multiple requests because of iterate mediator), you receive some responses and that what you have to deal with in the rest of the initial mediation : aggregate offers you a way to wait for all the responses, but the initial message is lost : you should save it in a property (type OM) and use something like payloadMediator inside aggregate/onComplete to compose the final message.
