Correlating an external message to an Execution

I have a simple process with an eventBasedGateway. I have 2 intermediateCatchEvents after the gateway; one has a timer and the other has a messageEventDefinition ("userCallback"). I have a test; the test works. However, it seems wrong. In my test, I create a process instance: Map<String,

I don't understand how Executions are related to process instances,

Here is the answer

These 2 queries get me to the Execution I want:
      Execution processEx = runtimeService.createExecutionQuery()
              .processInstanceBusinessKey("abc")
              .singleResult();

      Execution messageListener = runtimeService.createExecutionQuery()
              .processInstanceId(processEx.getProcessInstanceId())
              .messageEventSubscriptionName("callbackMessage")
              .singleResult();

I was expecting the following to work, but it does not:
      Execution messageListener = runtimeService.createExecutionQuery()
              .processInstanceBusinessKey("abc")
              .messageEventSubscriptionName("callbackMessage")
              .singleResult();

It seems to me that there is a kind of parent/child relationship here and I feel as though an ExecutionQuery on business key should return all Executions which are associated with the ProcessInstance which was created with said business key.

I'm just complaining, when you get down to it.

Indeed, the executions are actually a tree of executions:
