Re: UseOriginalAggregationStrategy in Camel 2.4
The original Exchange would be the oldExchange parameter on the very first
invocation of the AggregationStrategy.
So what you can do use to use a AggregationStrategy without extending the
UseOriginal, and just always return the oldExchange. And you can then just
add the headers from the newExchange to the oldExchange.

Did anyone succeed to use a custom Aggregation Strategy in Camel 2.4 that
will propagate original headers/body?
I'm afraid will have to switch back to Camel 2.3 in case there is no
solution for it....
Thanks.

Reading the release notes didn't help, basically they say the same thing:
"The aggregate method is now also invoked on the very first exchange.
Allowing the end users to be in full power.
At this first invocation the oldExchange parameter is null."
Thanks Claus.

davsclaus, thanks for the replay but seems that this doesn't work. I have a
null oldExchange on the very first invocation.
Seems that calling the aggregate() method with null OldExchange for the
first exchange was introduced in Camel 2.0 and there is no mention of
changing this in the documentation: http://camel.apache.org/aggregator.html
