[jira] [Updated] (CAMEL-5567) Add Multiple correlation Ids to the Aggregator component

["Alan Foster (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CAMEL-5567?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alan Foster updated CAMEL-5567:
-------------------------------

    Description: 
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
