I disagree - coupling Controller and Model contradicts the fundamental tenet of MVC which is separation of Model from the Controller and View UIs. As I understand it, the main benefit of MCV is that the Model knows the minimal possible about the Controller and View UIs. Most pundits indicate that the only relationship between a Model and View is that of the weakly typed observer pattern. I should point out that the mod_perlish MVC as described so far in these threads is only loosely based on the MVC pattern, which was originally designed for more traditional stateful user interfaces than web browsing. Here are some MVC pages that indicate Models should NOT be closely linked to Controller, and that in fact the relationship between the two user interface components [ie Controller and View] may be stronger. http://ootips.org/mvc-pattern.html And the MVC relationships are covered, esp on page 5 of this http://www.cs.indiana.edu/~cbaray/projects/mvc.html and there are some good pictures on this link http://www.object-arts.com/EducationCentre/Overviews/MVC.htm which also says: 'What we really want, though, is a tight coupling between AM and View but a loose coupling between Domain Model and View' I parse this as 'tight coupling between Controller and View but a loose coupling between Model and View' £0.02 Regards Jeff
