Hi George, PageRenderLinkSource is a part of the web framework. I mentioned before that you could split your app into 2 modules: api - depends on tapestry-ioc web - depends on tapestry-core
The test case I setup for you only tests the api stuff (tapestry-ioc). If you split into 2 modules this would be easy to see (since PageRenderLinkSource would not be on the test classpath).
