Issue - 66 - Zero or multiple matches of correlation set
Status: open
Date added: 19 Sep 2003
Submitter: Ricky Ho
Date submitted: 16 September 2003
Description:1) When an incoming message matches multiple process instances, which one will get the message ?
e.g. ProcessA is executing
<receive portType="PT1" operation="oper" ... createInstance="yes"/>ProcessB is executing
<receive portType="PT1" operation="oper" ... createInstance="yes"/>An instance of processC is executing<receive portType="PT1" operation="oper" ... createInstance="no"/>Lets say someone invoke "PT1/oper" and it matches the correlation set of the processC instance. Who gets the message ?
2) When an incoming message matches zero process instances, does the sender get a fault ? or the message will be queued until a matching process instances gets it later
e.g. A sender invoke "PT2/oper2" but no process is listening in that.
