Subject [jira] [Commented] (CAMEL-5567) Add Multiple correlation Ids to the Aggregator component
Date Tue, 04 Sep 2012 22:23:08 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-5567?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13448115#comment-13448115

Hadrian Zbarcea commented on CAMEL-5567:
----------------------------------------

But that would still be one expression, albeit a composite one, isn't it?

> Currently the aggregator component allows users to specifiy one expression that they
would like to use for aggregation
> It would be nice to add many different correlation expressions for all of the different
payload contents that an aggregator can receive
> For instance it may look like 
> {code}
> <camelContext xmlns="http://camel.apache.org/schema/spring">
>     <route>
>         <from uri="direct:start"/>
>       
>         <aggregate strategyRef="aggregatorStrategy" completionTimeout="3000">
>             <correlationExpression>
>                 <!-- If this xpath returns nothing try the next expression etc -->
>                 <xpath>/AcmeServiceResponse/CorrelationId/text()</xpath>
>                 <xpath>/FooResponse/Id/text()</xpath>
>                 <xpath>/CorrelationKey/text()</xpath>
>             </correlationExpression>
>             <to uri="mock:aggregated"/>
>         </aggregate>
>     </route>
> </camelContext>
> {code}
> I wonder what your thoughts are on this suggestion? If it seems like a good idea I can
start to make a patch for it
