That's not quite right. onValidateFromXYZ() ist called for field xyz as soon as that field
validates. You can give it a parameter that gets populated with the field's value. You can't do
cross-field validation though, that's what onValidateForm() is for.

Something I've never done because it's not logical to have errors in "success".
BTW, I believe you mean onValidateForm(). onValidate() is called before values
are set and they can't be tested correctly.
Thanks Christophe, Uli, and Geoff for clearing this up.

And you'd be well advised to get in the habit of doing all the work in
onValidate() because errors occurring in onSuccess() won't display
properly:

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?
