Validation and the delegate
Hi, I have just started on a new application with Tapestry (using
3.0beta4 this time). I have encountered a few problems. Maybe some of
you can explain to me the proper usage in the following case.
The page is a complex form containing a few ValidFields which use a
delegate to record the errors. My delegate extends the
ValidationDelegate class. I am trying to add a few other error messages
to the Delegate for some extended data validation (for instance "the
password and the confirmation password are not equal").
public void formSubmit(IRequestCycle cycle) {
ValidationDelegate delegate =
(ValidationDelegate)getBeans().getBean("delegate");
if(!getPassword().equals(getConfirm())){
delegate.setFormComponent(null);
delegate.record(new ValidatorException("Parola nu este
confirmata"));
}
if(!delegate.getHasErrors()){
... process
}
}
My problem is that I do not know where I should clear this error. I
tried to do that in the detach() function yet this results in error.
Any assistance, hint appreciated

Thank you very much, I realy think the bean lifecycle is the key to my
problem. For some unknown reason even if it defaults to render the bean
seems to be kept after the page rendered until the next request. I will
investigate further.
Thanks again, Len

Resin xml parsers (was Validation and the delegate)
Posted by Marilen Corciovei <le...@nemesisit.rdsnet.ro>.
I finally tracked the problem to this post:
http://www.caucho.com/support/resin-interest/0205/0112.html. It seems
the default attribute is ignored so the solution was to add
<bean name="delegate" class="ro.nit.components.NitValidationDelegate"
lifecycle="request"/>

Re: Validation and the delegate (problem is resin specific)

Hi Erik,
The problem is Resin (3.0.6 in my case) specific. The delegate bean is
not destroyed when the page finishes rendering. I deployed the
application in tomcat and everything works as desired.
Output on after 2 page submits:
resin:
delegate = ro.nit.components.NitValidationDelegate@fccada
delegate = ro.nit.components.NitValidationDelegate@fccada
tomcat:
delegate = ro.nit.components.NitValidationDelegate@c26ede
delegate = ro.nit.components.NitValidationDelegate@1710be
Any suggestions?

Why do you need to clear the error? I'm not quite sure what you mean
by "clear" in this case - wouldn't you just redisplay the entry page
with the error messages hilighted? What is your <bean> lifecycle set
to? I think I use page for mine.
