Hello All,
I am using Struts Validation framework and I want to use strust validwhen condition.

I have beginYear and endYear. The difference between beginYear and endYear should be one. So i did something like this.



But it doesnt work. Does anybody have any idea how can I achieve this ???

Thnx in advance

I must confess to being a little disappointed in the validWhen validation rule. What you're allowed to put in the test expression is very limited, and does not include addition or subtraction.

I'd suggest writing your own custom validation rule for this.

what came across my mind when i read you post (it has nothing to do with you question though, but might be worth considering)

are you sure you need _this_ validation? if i had the user to enter two years, and if one needs to be the following year of the other, i'd reduce user input to just one field

;-)

is that an option for you special case?

Hello guys

you can personalize your own type of exceptions (i.e. MyDateException) and could be throw from a BusinessObject (using the simple methods of class Date) (to compare 2 dates)

is only my suggestion
