"Run TestCase" example not working

Hi,

I've imported the tutorial project into soapUI and currently try to follow http://www.soapui.org/Functional-Testin ... tests.html

When I set up my "Run TestCase" test step in a new TestCase under a new TestSuite in the same "Sample Project", my Return Properties list in the "Return TestCase Options" setup window is empty. I have to start the MockService, add the Groovy TestStep from that website and run it, before the setup window gets populated...

What am I missing?
(Surely that isn't the default behavior, having to run a script first? ;)

Thanks,

Chris
