validation with link only

[Steve Lowery <sl...@gatessolutions.com>]

I have a Form object whose only child is an AjaxSubmitLink.  The Form's
onSubmit() calls to a service to delete its model object (from the
underlying database).  I would like to add validation to make sure that the
model can be deleted (i.e. there are no foreign keys referencing it) before
attempting to do it.  I thought I could achieve this with an
AbstractFormValidator, but if I detect the error in the validate() method,
all of the error methods on AbstractFormValidator expect a FormComponent,
which I don't have.

What is the best way to accomplish validating a Form that does not have a
FormComponent?

Why do you need a form?  Just use an AjaxLink.  And, do the check in
the onClick() method.
