Please read the first paragraph of [1]. In short: submit gets fired regardless of the validation
outcome, success if validation was successful, failure if not. validateForm is fired after the
individual field's validate events and allows for cross-field validation.

Apologies if this is obvious, but I'm getting confused over how and
where onValidateForm() should be used. I have a page with search fields
in a form and also a grid for the results.
Currently I have:
public void onValidateForm()
{
if (title == null && issn == null)
{
searchHoldingsForm.recordError("Please provide a value
for Title or ISSN");
}
}
public void onSubmitFromSearchHoldingsForm()
{
// perform database access using the form fields...
...
However, the onSubmit...() will be called even if there is an error. Ok,
I could use a Boolean and set it in onValidate() and then bail out in
onSubmit...() if there is an error. Or I suppose I could dispense with
onValidateForm() altogether and set the error messages directly in
onSubmit...() Or perhaps I should keep onValidateForm() and do the DB
stuff in onSuccess()?
What is the correct way to proceed and why?
