I have two beans (controllers), one from a Menu and other from the showing page (what i have selected previously from the menu).

The page have a few inputs and works perfect when i call page controller methods like "create", "destroy", etc, using commandbuttons.
But, when I call these methods from the menu controller the data from inputs isnt in the object.

That is the way i call the method from my Menu Controller:

Map sessionVars = FacesContext.getCurrentInstance().getExternalContext().getSessionMap();
(SYSuserController)sessionVars.get("SYSuser")).create();
