title: using RichFaces and PrimeFaces in the same application
body: <p>Can RichFaces (either 3.x or 4.x) and PrimeFaces (either 3.5 or 4.0) be used in the same JSF 2.x application? Will they coexist nicely?</p>
  
  <p>My goal is migrating from RichFaces 3.x to PrimeFaces. I would like to start by using PrimeFaces for a new submodule of my web application, and eventually migrate everything.</p>
  
  <p>It would be fairly easy to set up a simple hello-world sized project and try it out; I am asking here because I wish to know if there are some problems when doing this on real-life sized projects.</p>
