--------------------------------------------
Gavin,
I have a pageflow where from one page, I transition (with a validation action method --
void return) to a decision node. The decision node is supposed to determine if there are
errors present and decide which page to transition to next. I was reading the Seam
documentation where it said that it's preferred that actions have simple values, e.g.
"next", instead of using the result of an action method -- the intent was to
decouple the business logic and place that in the pageflow instead of the JSP.
I was making an inductive jump and assumed that the same thing should happen within
pageflows. I could return something other than void from my validation method, but at
that point I'm coupling the business logic and the pageflow logic. That would make it
more difficult for me to reuse that validation method, aggregate validation methods, etc.
If there's already an established architectural or use pattern that does the same
thing, I'd be happy to adopt it. I'm a bit new to the Seam world, so it's
very possible (probable most of the time) that I'm simply doing things the wrong way.
Not able to query FacesMessages to determine if any messages have
been added.

Project: JBoss Seam

It would be helpful to determine if messages have been added to FacesMessages. At this
point, it is impossible to determine if messages are present in FacesMessages.
