The action stack seems to be a useful component to some people when starting out with the Zend Framework.

This part of the Framework causes the dispatch to loop. This is a costly process, as it involves quite alot. It also adds some further issues to your application design, such as where you should put code. for example if you have some code in your predispatch, and your looping through two actions in that controller, that code will be run twice. This is obviously, not good, and quite un-needed. Further complications can be added when it comes time to add ACL or authentication.
