Validation error displayed by parent component?

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!

Folks,
I've just figured out a solution. Just remove the <tr:panelLabelAndMessage> tags and it will do. But Trinidad is very new to me, and I still don't quite understand what is going on behind the scene here. So it would be great if anyone could kindly give me some explanation. Thanks...
