TestSuite Mock should recieve 3 responses

Little update.

I found that i can use groovy to start my mocks

so now i have a start step, an request step and a stop step
the start step

def project = testRunner.testCase.testSuite.project
log.info project.name
def myMock = project.getMockServiceByName("My-Mock")
def myMockRunner = myMock.start()

myMockRunner.setLogEnabled(true)
// place the object on the context
context.setProperty("myMockRunner",myMockRunner)

the stop step

def myMockRunner = context.getProperty("myMockRunner")
if(myMockRunner.isRunning()){
 myMockRunner.stop()
}

the only thing that i now have to do, is check how many request the mock received. Due to the lack of documentation in the soapUI api, I don't find how i should do this. Write my own listener or is it possible to do this with the code available?

I allready tried to configure a counter that places a value on the context of the Mock service, but in the test suite, I cannot access the context of the Mock Service
