Make sure your correlation expression would give the same result for the 2 messages, otherwise the aggregator EIP cannot match the 2 messages. And then it wont call the strategyRef to "merge" the 2 of them. So can you double check that header is the same for the 2 of them? > Thanks for any help ! > > > > -- > View this message in context: > http://camel.465427.n5.nabble.com/aggregator-aggregation-completion-tp5717567.html > Sent from the Camel - Users mailing list archive at Nabble.com. -- Claus Ibsen ----------------- FuseSource Email: [email protected] Web: http://fusesource.com Twitter: davsclaus, fusenews Blog: http://davsclaus.com Author of Camel in Action: http://www.manning.com/ibsen
