You don't have to call the controller from the loop.html page. Even though the URL is /[app]/[controller]/loop.html, web2py does not start with the execution of loop.html and then call the 'loop' controller from there. Rather, the order is reversed -- web2py executes the 'loop' controller and then passes its returned value (which is a dictionary of values) to loop.html, which is then rendered by the templating engine. On the AlterEgo page you are referencing, the second paragraph of the introduction explains this. For more details, see http://web2py.com/book/default/chapter/03#Say-Hello and http://web2py.com/book/default/chapter/04#Dispatching. Note, by default, when a given controller action is executed (e.g., 'loop'), web2py looks for a view with the same name (e.g., loop.html). However, you can explicitly tell web2py to call a different view by setting response.view to a different view. You can also call response.render explicitly in the contoller and return the complete rendered HTML instead of a dictionary of values (in that case, the HTML is returned directly). You don't usually need to do this. For details see http://web2py.com/book/default/chapter/04?search=response.view#response. Anthony
