Re: validation for optional fields
You are completely correct Matt. In our situation, there were other
reasons that led us to create our own versions of the struts validations -
I won't bore anyone with those details. The point I was really getting at,
is that specialized applications of the struts validations can be easily
accomplished. The need to "extend" a struts validation has to be there.
In our app, we use a combination of the canned struts validations and some
of our own validations that apply logic that is specialized for our
specific needs.
I probably read too much into the question... :-)

Maybe I'm missing something here, but why can't you just setup the
validation to do the integer validation without the required validation?
Integer does not depend on the required validation, so it should be fine -
if there is nothing in the field the validation will just return true.
Sample code in validation.xml would be:

Re: validation for optional fields
Oops, didn't realize you were using 1.1 - not sure of the behavior there.
Looking at the code, it appears as though the validateInteger method returns
null if the field is blank, which would seem to indicate this wouldn't work
for you. (But I'm not sure)
I know my suggestion works on the 1.2 nightlies (Well...the nighlies from
january, which is what I have been using for my project...)

RE: validation for optional fields
We have a similar situation with our validations. We created our own
validators to handle those situations. For the javascript, we cloned the
javascript for the validation and added logic to apply the validation when
a field was populated - very easy. For the server-side validation, our
java class first insured that the field was not blank, and then invoked the
appropriate from the Struts validator, also very easy.

hi,
if you are validating in your form or action class you can check if the
field is not empty (!= null or !equals("") and then check for correct
int value.
