Thanks for the reply.
My error was to believe that handleValidationErrors was called when
validation fails, when, in fact, the method is called whenever there are
ValidationErrors in the actionbeancontext (as clearly stated in the
javadoc, btw). This can seem the same at first sight, but theres a rough
corner. If you try to forward to *the same* action but different event,
handleValidationErrors will be invoked again, possibly resulting in an
infinite loop.
On a side note, while testing my discoveries, Ive found that the event gets
lost when a forward is made to the same action
Dont know if this is a
known issue. Rudimentary sample code:
public Resolution handleValidationErrors(ValidationErrors errors) throws
Exception {
String event = getContext().getEventName(); // First
validation error is triggered in the event persistUserData
if (!event.equals("execute")) {
return new ForwardResolution(EditUserAction.class,
"execute").addParameter("user.id", user.getId()); // Execute event gets
ignored, resulting in an infinite loop
} else {
return null;
}
}
Sorry about the clumsy explanation.
Thanks.

Hi Hector,
I am not a writer of this entry but I believe it means method will be
invoked when validation not passes (fails).
So, lets say you have a form that contains some validation errors, normally,
user will be presented with your form and validation errors.
However, if you implement ValidationerrorHandler intrerface, before
presenting user with the form,
method handleValidationErrors() will be invoked,
and there you can decide what to do with errors (e.g. remove them, add more
errors etc)
hth,

Hi all.
Just noticed (after scratching my head for a couple hours) that I had
misunderstood the statement is invoked when validation fails in the
Validation Reference wiki. Can I have a wiki user to try to clarify it?
