How I did it:
public static void
contributeFieldValidatorSource(MappedConfiguration<String, Validator>
configuration)
{
configuration.add("myvalidator", new MyValidator());
}

I'm REALLY swimming lost here, however I want to use a custom Validator for a
form Select widget.
I have the server side down OK. I figured I would try to attach the validator
in the template as well --
t:validator="NotEnumElementValidator=UNSELECTED" -- but I don't know how to
contribute the validator so I can use it here.
I'm trying obvious things like in my ApplicationModule class:
public static Validator<...> build();
and
public static NotEnumElementValidator buildNotEnumElementValidator();
But no luck trying! I can't find the concrete example in the documentation.
Can anyone tell me how I'm supposed to do this?
--About this validator too: it is supposed to take an Enum element that is an
invalid selection from a list: I use the old rogue method of having the first
item in the Select list say something like "[You must select...]" and then
test if the user has chosen some other item. Is this still a modern method of
validating a Select element?
This kind of validator seems like it would be a nice fit with the Bean edit
form, which seems to support enums too.
Anyway, thanks in advance.
Ciao.
Steev Coco.
