Sequence Runner and Signals

Question

I've got a unit test where I want to test reading from a local sqlite database.  Obviously I need to write a record before I can read it.  I've written the sequence below but I'm getting an "Asynchronous Event Received out of Order" error:
[Test(async)]
public function testRead():void
     LOG.info("testRead()");
     var runner:SequenceRunner = new SequenceRunner(this);
     var signal:SignalAsync = new SignalAsync(SERVICE.createSignal);
     runner.addStep(new SequenceCaller(SERVICE, SERVICE.create, [person]));
     runner.addStep(new SequenceWaiter(signal, SignalAsyncEvent.CALLED, 1000));
     var signal2:SignalAsync = new SignalAsync(SERVICE.readSignal);
     runner.addStep(new SequenceCaller(SERVICE, SERVICE.read, [person._id]));
     runner.addStep(new SequenceWaiter(signal2, SignalAsyncEvent.CALLED, 1000));
     registerFailureSignal(this, SERVICE.errorSignal);
     handleSignal(this, SERVICE.readSignal, testReadResultHandler, 3000, person);
     runner.run();
Since SequenceWaiter required an event I created a new SignalAsync which fires a SignalAsyncEvent when the signal is triggered by my service.  I'm sure I'm doing this totally wrong so any help would be great. The person object is created when the test beings.
Thanks,

Rather than using Signals, why don't you just nest your Sequences that you want to run? Something like this:
var sr1:SequenceRunner=new SequenceRunner(this);
var sr2:SequenceRunner=new SequenceRunner(this);
//add some sequence steps to sr1 here
sr1.addStep(new SequenceWaiter(someEventDispatcher, someTriggerEvent, 10000));
sr1.addAssertHandler(
function(event:Event, passThroughData:Object):void
     //add some sequence steps to sr2 here
     sr2.addStep(new SequenceWaiter(anotherEventDispatcher, anotherTriggerEvent, 10000));
     sr2.addAssertHandler(
     function(event:Event, passThroughData:Object):void
          //do some assertions here
     , null);
     sr2.run();
, null);
sr1.run();
