Change side menu controller on the fly?

[cinnabarhorse]

First of all, thanks for the great control. I'll be using it in my upcoming chat app. I've done a little customization and added a second menu controller (called right menu controller) so that the user can swipe left and right for different menus. My only issue right now is switching out the menu controllers on the fly when the user loads different pages. For instance, on one page I want to display all of their friends, but on another page I want it to display search criteria.

Could you point me in the right direction of how to do this? I tried swapping out the view controller in the mainController's viewWillAppear method but it didn't give the desired effect. Thank you.
