Make your managed-bean session scoped.
If you are using MyFaces you can use PageFlowScope. If using Seam then use Conversation scope.
If pageflowscope or conversation scope is not available, then use session scoped beans. In addition you can use PhaseListener to initialize or execute specific methods before the page gets called. In you case if the flow is page1 -> page2 -> page3, then initialize the session scoped bean in PhaseListener if page1 gets called.
I'll update with more info if you need.
