> 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.
