Re: Only want to validate a text field if checkbox is checked ...
how?
So you are the author of the optional validation framework? That is
excellent. I was reading the page but am still missing the gist of the
example. How would you say, "If element A contains this value, then apply
this validatino rule to element B?"
Thanks, - Dave

hi,
as mentioned in my previous post, i added the functionality to the
validation strategy for @RequiredIf [1]
the changes are compatible with existing versions of extval. i'll provide
details about using it with already released versions, if someone would like
to use this improvement with a released version instead of the next
milestone.
furthermore, i added some information to the wiki [2] (the section
"conditional validation via cross-validation")

hi,
since it's a nice idea to have an out-of-the-box support via @RequiredIf,
i'm going to add such a feature to the validation strategy for @RequiredIf.
it will be available in the next milestone (which will be published quite
soon).

hi,
basically the current implementation of @RequiredIf is designed to be used
in combination with two text-input fields. anyway, it's quite easy to solve
the requirement with the cross-validation mechanism of myfaces extval. you
can also implement a @ValidateMyCustomConstraintIf based on the
infrastructure of extval. i'll create a wiki which describes the required
steps.
additional information:
if the information is already available in a bean, you can use
@SkipValidation as well. (however, that's not the case in your use-case.)

The optional validation framework is ancient at this point. It was a
short-lived, flawed project. I don't recommend using it as is, but
maybe you can use pieces of the source code as examples to accomplish
some of what you need.
Your best bet is to either reuse validateCompareTo
(CompareToValidator) from Tomahawk or write your own validator using
that Tomahawk component as a model. You could submit it back as a
requiredIf validator to MyFaces. This is the approach I would take.
Here's a generic thread on conditional required fields -- one of the
few I could find on the subject -- and it also talks about using the
compare-to strategy above.
http://forums.sun.com/thread.jspa?trange=15&threadID=500322&forumID=427&tstart=0
I see there's also a @RequiredIf annotation mentioned in the ExtVal
docs. I don't know if it's also available as a standard non-annotated
validator, though.
One other remote possibility is to see if a subForm can be configured
to be able to do what you need.
