How to write a customized valdation, that validate by comparing one
field to another_
I need to validate two fields on my webpage, two dates, and I need to check if one date is greater than the
other. Is this possible? Have I access to the other fields from within my validate method or is there another
way of doing this (or do I have to check this in my save method)?
Regards,
BTJ

As far as i know validation in the JSF spec is component based, so if you
want to validate a form (like you) you should follow a different way, you
can add a hidden input after the components you want validate and write your
validator method to this hidden component validator. (You can read detail of
this trick at the Core Faces book's validation section, it is avaible online
http://www.horstmann.com/corejsf/).
When following this way i encountered a different problem, i could not get
the request values (model values are not updated at the validation phase)
at the validation phase, so i added dataModel.processUpdates(facesContext)
line into the validation method. Advanced developers may advice a different
way may be?
regards...

validateCompareTo is exactly what you need, and it's stable. I wrote
it to compare date fields, so this is its most-tested configuration :)
I'll probably push to have it promoted from the sandbox to tomahawk pretty soon.
The only issues holding it back (that I know of) are that there are
some hardcoded strings in the code that need to be moved to
localizable message properties.
If you'd like to speed up the promotion process, feel free to submit
patches fix this issue.

+1 for validateCompareTo. This is an extremely useful validator which we use
extensively.

You could do it using validator. Read "*JavaServer Faces" of Hans Bergsten.*
