Exception handling - JSF swallows exceptions in certain phases
--------------------------------------------------------------

                 Key: JBSEAM-2597
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2597
             Project: JBoss Seam
          Issue Type: Feature Request
          Components: Core
            Reporter: Shane Bryzak
             Fix For: 2.1.0.GA


I can't reproduce this right now but I'm sure I spent several hours
with a debugger only to find out that I had a typo in a value binding
and that the exception was completely swallowed during an early JSF
phase (UPDATE MODEL probably). There was nothing in the log, the
action phase just never executed. This is a major issue (obviously)
for another subtle reason: Beginners have trouble understanding the
JSF lifecycle and processing phases - I know I did. You begin to hate
JSf when you don't understand why a certain phase does not execute.
I'd start reproducing it by generating an NPE in a value binding
setter, that should do it.
