I was gonig to point you at the website page about Dialog, but I can see now
it's not particularly helpful :-).  There's only one sentence (the very last
one) that contains the key bits.  Basically, the only current way to enter a
dialog is to have some action on a non-dialog page return a logical outcome
string of the form "dialog:xxxxx", where "xxxxx" is the name of the Dialog
you want to start.  This causes Dialog's version of NavigationHandler to
kick in, and transfers control the the starting state.

You can do this directly, for example from a hyperlink:

    <h:commandLink ... value="Start Login Dialog" action="dialog:Log in"/>

or indirectly via the value returned from an action method:

    <h:commandLink ... action="#{backingBean.myaction}"/>

    public class MyBackingBean { // mapped to managed bean name
      public String myaction() {
        return "dialog:Log in";
