Is there an easy way to make validation conditional? For instance I
have a set of radio options. If the user chooses option1, I'd like
the fields under option 1 to be validated. If they choose option 2,
I'd like the fields under option 2 to be validated and so on.
I looked a bit at the Required validator class, but I couldn't
figure out how to check if another field was set to another value.
I was trying to figure out how to do something similar a little while
back. I tried a bunch of different things before I arrived at my
current solution. What I do is have something like the following for
a component definition in a page spec:
<binding name="validators" value="fieldRequired"/>
Then, in the page class I have something like:
@Bean
public abstract Required getRequired();
public Validator getFieldRequired()
{
if (true == someCondition)
{
return getRequired();
}
return null;
}
I haven't tried this with a list of validators, but I suppose it
would work just as well.
Well thats clever. Works great for me. Thanks!

Actually I have one issue. I'd like to impose a maxLength on some of the
fields. I can't seem to figure out how to mix regular ol' validators and
my validator which is a field:
<binding name="validators" value="validators: maxLength=2, fieldRequired"/>
That was the best I can come up with... I know you can use a $ to
reference a bean, but this is a property on my page. How would I
reference that?
