I've written validation methods myself. The two dates are used to define a time
frame to generate a report. The 1st date cannot be a future date, and the 2nd
date cannot be earlier than the 1st date, nor can it be a future date.
Unfortunately, the error message in FacesMessage is always displayed twice.
I've googled about and explicitly set only "detail" but not "summary" (I've
tried the other way, and in that case, there will be no error message
displayed). From the expanded html, it looks like the repetition is either from
<tr:panelBox> or <tr:panelLabelAndMessage>, but I just don't know how to
disable displaying the message by a parent component. Can anyone shed any light
on this? Thanks a lot!
