Subject Re: <redirect /> and FacesMessage problem
Date Mon, 23 Apr 2007 20:19:09 GMT
i have thought of using a validator.  the only problem is that if the 
value is null, the validator isn't called.

the message needs to warn/remind user (does not give an error and let 
the user continue) that he/she has left these fields blank.  i cn't use 
required="true" either since we allow fields to be null and all we do is 
display the null values of the previous page.  It's weird I know but 
well.... <sigh>

therefore we do the validation on the event method and build the 
Messages there as we redirect the user to the next page.
