call controller from another one

Wiredesignz please take it easy. There are legitimate uses for calling controllers in controllers like for instance in a modulated site. Modules don't always have to be aware of the general lay-out or other user actions.

Like esra pointed out there are other design patterns which aren't used in the CI framework but have al lot going for them like the HMVC pattern.

The limitations of MVC can result in jack-of-all-trades libraries and model like controller hacks, is that a good way to go?
