When experimenting with the examples buggy code that I added often causes exceptions ;-) It seems that Seam tries to redirect to the debug page, but fails. For example I added a dummy exception in the seam-pay example (alwayws throwing a RuntimeException in PaymentController.saveAndSchedule()). When I try to save a payment Seam seems to catch the exception and tries a redirect to http://127.0.0.1:8080/seam-pay/search.seam/debug.xhtml?conversationId=4 which result in a 404. When I manually type the following URL in the browser, I see the debug page, including my exception just fine: http://127.0.0.1:8080/seam-pay/debug.seam How comes? I can't make sense of the documentation. After reading it I expected an exception entry in pages.xml, but there's nothing. What makes Seam try the redirect and why does it fail?
