Show how <pick/>, where a process instance execution can be specified based on a
particular received event. The received event can be <onMessage/> or <onAlarm/>.
Additionally user have to define a correlation set and refer it in each event in-order
to determine the correct execution path.
Here the property points to a particular message element which is called <Deck/>
in the dealDeckRequest message type.
eg -
<dealDeck><Deck></Deck></dealDeck>
So once a message of the type dealDeckRequest is received, an instance of
correlation set will be created based on the value of the element <Deck/>.
In this sample, when a
dealDeckRequest
message is received a process instance is
created due tocreateInstance="yes". As well a correlation set instance
is also
created due toinitiate="yes".
Suppose there's a incoming message for a operation defined in <onMessage>. So
once the message is received to the process, it'll be verified with correlation set
instance. If there's an existing process instance, which is compliant with the
correlation set instance, then the instance will execute the particular set of
activities defined.
If the incoming message's operation is "pickSpade", and the partnerLink is
"IncomingLink" , and the incoming message is compliant with the correlation set
instance of the process instance, following activities are executed.
