Not possible?
Sometimes a validator needs to look at input from another field to see
if it is valid (ie password/confirmPassword). I know it's easy to do
in onValidateForm, but I'd like to see how to do it in a nice modular
Validator. I'm looking for something like:
public void validate(Field field, String sourceFieldId,
MessageFormatter formatter, Object value) throws ValidationException {
Component page = ((AbstractField) field)._resources.getPage();
try {
Method getter =
page.getClass().getDeclaredMethod(getMethodName(sourceFieldId));
String sourceValue = (String) getter.invoke(page);
if (value == null || !value.toString().equals(sourceValue))
throw new ValidationException(buildMessage(formatter,
field));
} catch (Exception e) {
log.error("No public getter field in page for: " +
sourceFieldId);
}
}
but can't do that (the only problem being the private _resources). How
can that be done in a Validator? I can't inject anything. I don't
actually need to make my own field which exposes the
ComponentResources, do I?
Thanks.

How can you get access to an arbitrary Field from inside a
Validator, given its id? In t4 it was relatively easy to grab the
form and from there grab a field.
Thanks,
