Rahul,
I an getting the following when I click on the home link. It appears that the
dialog
is still running even though it was stopped.

What is the name of the method, or where do I configure it, that is
called when the outcome, does is not configured?
In the above example page's header/footer define the outcomes "home",
"logout", and "menu". These outcomes are currently handled by
faces-config.xml, and I agree with your statement about avoiding the
modeling of "global" site navigation in each dialog.
<snap/>
Lets say outcome "home" is actually a commandLink, so simplistically:
<h:commandLink action="home" value="Home" />
This, by itself, would mess with an active dialog. Instead:
<h:commandLink action="#{globals.home}" value="Home" />
would ensure that we clean up correctly if there is an active dialog,
where:
// In the managed bean "globals" --
public String home() {
stopActiveDialogIfAny(); // the two lines of code from before
return "home"; // faces-config nav rules takes over here
}
Similarly for "logout" and "menu". Also may want to check with user
via onclick or suitable event handlers before wiping out the dialog.
