the process designer has nothing to do with the userinterface (yet). A custom controller is no userinterface element. The controller is the piece of code that handles the userinterface requests. Which userinterface elements (jsf components in the case of jBPM) can be used is completely up to the way the forms are handled. In jBPM 3.1 you cannot influence this at all without building your own or adapt the exsisting controler. In the upcomming jBPM 3.2 (currently only in cvs) there is more flexibility, but if it is enough for your needs remains to be seen and depends on your needs. So If you feel up to it, checkout the CVS head and play with it. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3960177#...
