There is no access to the bound message in action parameters.

When an action is fired the message should be available in the otherAttributes Map with key specified using the bind attribute in
the <receive/> element. Right now I have to specifically set the
message (!!!) which I don't want to do because it ends up in
the caseAttributes and I don't want the message persisted. So
we need to make the message available in otherAttributes when actions are fired.

01) <process initiation="message" id="message-flow" package="tambora">
02) <sequence>
03) <receive type="buyer.purchaseOrder" bind="message">
04) <jelly:action>
05) <j:set var="poId" value="$

"/>
!!! <j:set var="message" value="$

/>
06) </jelly:action>
07) </receive>
08) <action actionId="store-purchase-order"/>
09) <action actionId="queue-purchase-order"/>
10) <receive type="buyer.orderConfirmation" bind="message">
11) <ognl:correlator confirmationPoId == poId"/>
12) </receive>
13) <action actionId="store-order-confirmation"/>
14) </sequence>
15) </process>
