Aggregate two JMS messages from two different consumers - jms

Question

I have two jms consumers, each in a different flow. I want to use another flow to aggregate the messages of thoe two messages. and also need to keep the correlation Ids as i need to split the payload and send back the messages.
<flow name="integration-consumer-client1" doc:name="integration-consumer-client1">
<jms:inbound-endpoint doc:name="JMS" connector-ref="Active_MQ" queue="client1.publish"/>
<logger message="Consumes Client One = #[payload]" level="INFO" doc:name="Logger"/>
<logger message="Client One Correlation = #[message.correlationId]" level="INFO" doc:name="Logger"/>
<vm:outbound-endpoint exchange-pattern="one-way" path="client1" doc:name="VM"/>
</flow>
<flow name="integration-consumer-client2" doc:name="integration-consumer-client2">
<jms:inbound-endpoint doc:name="JMS" connector-ref="Active_MQ" queue="client2.publish"/>
<logger message="Consumes Client Two = #[payload]" level="INFO" doc:name="Logger"/>
<logger message="Client Two Correlation = #[message.correlationId]" level="INFO" doc:name="Logger"/>
<vm:outbound-endpoint exchange-pattern="one-way" path="client2" doc:name="VM"/>
</flow>
<flow name="integration-internetsolutionsFlow1" doc:name="integration-internetsolutionsFlow1">
<scatter-gather doc:name="Scatter-Gather">
<vm:inbound-endpoint exchange-pattern="one-way" path="client1" doc:name="VM"/>
<vm:inbound-endpoint exchange-pattern="one-way" path="client2" doc:name="VM"/>
</scatter-gather>
</flow>
I tried to use the scatter gather with two inbound VMs but get the following error:
Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'vm:inbound-endpoint'. One of '{"http://www.mulesoft.org/schema/mule/core":annotations, "http://www.mulesoft.org/schema/mule/core":custom-aggregation-strategy, "http://www.mulesoft.org/schema/mule/core":threading-profile, "http://www.mulesoft.org/schema/mule/core":abstract-message-processor, "http://www.mulesoft.org/schema/mule/core":abstract-outbound-endpoint, "http://www.mulesoft.org/schema/mule/core":abstract-mixed-content-message-processor}' is expected.

The reason of the error is integration-internetsolutionsFlow1 doesn't have any inbound endpoint ..
What you can do is following :-
Use vm:outbound-endpoint to same path from both the flow
integration-consumer-client1 and integration-consumer-client2
Then in integration-internetsolutionsFlow1
<flow name="integration-internetsolutionsFlow1" doc:name="integration-internetsolutionsFlow1">
<vm:inbound-endpoint exchange-pattern="request-response" path="Your Path" doc:name="VM" connector-ref="vmConnector" />
<logger level="INFO" message="#[message.payload]" doc:name="Logger"/>
<!-- you don't require a setter-getter here -->
</flow>
The path of outbound VM from both the flow integration-consumer-client1 and integration-consumer-client2 should be same..
You no need a scatter-gather here .. since both the flow will disptch the payload to same VM path .. It will be receive by VM inbound endpoint
