Re: How to write a customized valdation, that validate by comparing one field to another_

[Murat Hazer]

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...

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)?
