I generally create a mock for the IRequestCycle (using EasyMock), so havent run into this kind of problem.
>From what I can guess from the code, you try to initialize the Tapestry system and have it along during the unit tests. Are there any real benefits to this, instead of using mocks? But anyway, you could extend the RequestCycle class, override its getPage method and have Creator construct a suitable page instance, couldnt you? >From Matt Raible <[EMAIL PROTECTED]>: > I'm in the midst of upgrading Equinox (http://equinox.dev.java.net) > from Tapestry 3.3 to 4.0.
