Setting the output exchangePattern in recipientList DSL

[Raul Kripalani-2]

Hi,

Was just about to open a JIRA improvement ticket to add the capability to
the recipientList DSL to override the exchange pattern. Following is the
ticket body:

Right now, the exchanges sent by the recipientList DSL absorb the exchange
> pattern of the incoming exchange. We should add a capability to overwrite
> the exchange pattern.

But just wanted to double-check just in case there's a way to achieve this
(other than using onPrepareRef) that I'm unaware of?

Thanks,

You can use the setExchangePattern before the recipient list to alter it.

But yeah maybe we should consider having to override it like you can do on <to>
Mind that this override is "local" only, and the MEP is not changed on
the original exchange, being routed afterwards.

Exactly, that would be the intention!
Here goes the ticket: https://issues.apache.org/jira/browse/CAMEL-5301.

Thanks, Claus.
