Typemock exception

Hi,
I am currently evaluating typemock so maybe this is a stupid mistake from my side.

But with the following code:

<TestMethod> _
Public Sub OnProcessChangedTester()
Dim fakeViewer As IMainViewer = FakeInstance(Of IMainViewer)()
Dim controller As New MainController(fakeViewer)

Using TheseCalls.WillBeIgnored
controller.UpdateMenu()
End Using

controller.OnProcessChanged(Me, EventArgs.Empty)

Using AssertCalls.HappenedWithExactArguments
controller.UpdateMenu()
End Using
End Sub

I get a typemock exception:

Test method PvUnitTest.MainControllerSequenceTest.OnProcessChangedTester threw exception: TypeMock.TypeMockException:
*** No method calls found inside using block.

The line number returned is the End Using line in the first using block

The above code is a shorter version of the intended test which contains several calls to the faked MainViewer. The asserts for calls to the methods in the faked object works OK.

It only this call to a method in the actual controller object that is causing problems.

I have tried it on both:
- VS2008 Pro with MS Test
- VS2008 Pro with Nunit and Testdriven.Net

The results are the same.

Thanks in advance for your help
