The failed state of the process instance does not allow the requested sendMessage action to be performed (Message: CWWBE0126E)
An attempt to send an event to a process instance results in an 'EngineProcessWrongStateException' message.
Reason
A common reason for this error is that a message is sent to a receive or pick activity to create a new process instance, but a new process instance cannot be instantiated. This situation occurs if the values that are passed with the message for the correlation set that is used by this activity match an existing process instance, which is already in the failed state.
Resolution
To correct this problem you must either delete the existing process instance, or pass a correlation set value that does not match an existing process instance. For more information about using correlation sets in BPEL processes, seeCorrelation sets in BPEL processes.
