I think I got it: I can use onvalidate and set the form.errors when the
exception is tripped. That way, the form is never successfully submitted.
Although now I have the problem where the form errors are displayed twice
for fields that have their own validate function set.
For example, setting the "requires=IS_INT_IN_RANGE(1,100)" for an INPUT()
will show up twice. Once underneath the input tag, and again in the html
where I set {{=BEAUTIFY(form.errors)}}
How would I disable the error display underneath the input tag?
