Hello Camel, I have a strange behavior with the aggregator component. After a few hours I still cannot explains what happens.
I have an aggregator define as <aggregate strategyRef="crgAggregatorStrategy" batchSize="3"> <correlationExpression> <xpath>/ns:message/ns:correlation</xpath> <!-- <method bean="crgAggregatorStrategy" method="correlationId" />--> </correlationExpression> <to ref="cbr"/> </aggregate> The xpath expression is the correct xpath expression and message have content. I also tried to set a constant or to use a bean returning a fix value but in all cases the oldExchanged variable is null. It would be great if someone could indicates where I made a mistake, Thanks in advance, Olivier -- View this message in context: http://camel.465427.n5.nabble.com/Aggregator-oldExchange-always-null-tp2805136p2805136.html Sent from the Camel - Users mailing list archive at Nabble.com.
