This is an area we've already identified for the 2.0 release. Search for "Zend_Controller 2.0" in the wiki for more details. We're aware of the issue, and while the design seemed reasonable originally, we've noted that the singleton has caused more issues than benefits. (Testing is one -- but that has been largely solved at this point.) That said, it's not a trivial undertaking at all to change, as it requires dependency injection throughout the entire MVC stack -- which will mean a lot of new paradigms in the code. Yes, this sort of thing cannot be done with a patch alone -- but the earlier examples likely could -- and I welcome you to do so. -- Matthew Weier O'Phinney Software Architect | [email protected] Zend Framework | http://framework.zend.com/
