Validation Complications - Validating only those fields displayed
in the form, and not the rest of the object in use
Hi all,
Quick Struts 2 validation question:
Is it possible to validate only the fields displayed in a form, when the
form's fields are part of a larger object that uses annotation validation?
The problem is that I am using one object across many forms, each form
contains some of the values for that object. When each form validates it
validates everything in that object with a validation annotation, even if it
is not contained in the current form.
It seems as though there should be a Validate only form contents option, am
I missing something?
Thanks in advance!
George

Great! I guess I'll be switching to XML validation or action specific
validation.
Thanks for the info :)

This sounds like an impedance match between the validation rules you've
set up on the object in question, and how you're actually using it. If
you annotate the object with validation rules, all of them apply any
time the object is validated. You're effectively saying that the object
is only valid if those validation rules are all met.
If you need to use different validation rules in different uses of the
object, you'll need to pull the validation rules out of the object
itself and associate them with just the actions they apply for.
AFAIK, there is no way to toggle the application of individual
validation annotations on an object on and off. If you only want to
validate the contents of the form, tie the validation rules to the form
itself.
