[Aggregator] completionPredicate evaluated only once ?
Hello,
I still have some issues with the aggregator component.
According to my tests the completionPredicate is evaluated only once the
first message is received.
After that the method is not executed anymore.
Is there anything that could provoke this behaviour ?
I put here under the trace of my test
running aggregate method
old Exchange: null
new Exchange: Exchange[Message: <ns:message xml ...
running isCompleted method
old Exchange: Exchange[Message: generic message ...
new Exchange: Exchange[Message: <ns:message xml ...
running aggregate method
old Exchange: Exchange[Message: generic message ...
new Exchange: Exchange[Message: <ns:message xml ...
running aggregate method
old Exchange: Exchange[Message: generic message ...
new Exchange: Exchange[Message: <ns:message xml ...

Great that it works for you now. And I hope you didn't have any other
"hickup" upgrading to Camel 2.4.

Thanks

I see,
That explains my observations.
I will switch to 2.3+ as soon a possible.
Thanks for your explanations on this matter

You cannot mix and match the different completion options (eg batch,
timeout, predicate) etc. in 2.2 or older.
And the completion predicate is only fired once, eg when the batch is
about to be send out.
And there is no workaround in 2.2 or older. You gotta live with it as it is.
In 2.3 onwards the conditions is evaluated on-the-fly when a new
messages arrives.
And it support persistent store and whatnot.
