I think so, look at this.
http://www.learntechnology.net/validate-manually.do
My implementation down here.
/*** CODE ***
/**
* This method is used to execute validation rules <br>
* The good-part,
* <br>1. can chose to not validate if cancel is submitted .
* <br>2. If validate exception is found the Form/Page can be
reInitialized and shown properly again.
* <br>
* The bad-part, normaly the user sets validate="true" in config but
this
* can no longer be done, can feel strange. <br>
* This method is used with recommendation from --> <br>

Subject: Bean Population When Form Cancelled
Hi all,
I have a form that uses validator to check for simple validation like
making
sure that a cash amount is a double. I have the "cancel" button on the
form
set so that if it is pressed that validation does not take place. This
is
great except when you type a letter into the cash text box and then
press
cancel. The form gets returned along with the invalid cash amount, the
BeanUtils attempts to populate the form and the whole thing falls over
with
an exception.
Does somebody have a strategy for dealing with this situation? Is there
a
way of telling struts that if the cancel button is pressed that NO bean
population should take place?
All help appreciated.
Cheers
Tom
