I just want to build a working login page and copied the code snippets here http://tapestry.apache.org/forms-and-validation.html and added them to the quickstart application - my versions appear below. When I navigate to the Login page it returns: Embedded component(s) form are defined within component class com.epulse.tapestrydemo.pages.Login (or a super-class of Login), but are not present in the component template (classpath:com/epulse/tapestrydemo/pages/Login.tml). Has anyone a simple login page example that works, or can help with the above?
