Thanks for that fantastic reply. Yes, in fact, the Component annotation is
exactly what I was missing. Don't know why I didn't see it before...
And that Input Validate page you refered me to is quite a help. Reading
avidly.
Thanks!
Marc

Hello Marc,
I think you want the @Component annotation instead of
@InjectComponent. The latter is "Used exclusively inside a mixin to
connect the mixin to the component to which it is attached."[1]
I haven't tested whether this will solve your problem, but it seems
likely.
A good starting point for basic form validation is probably the 'Input
Validation' page of the online documentation[2]. It comes with a
simple example and a lot of useful info.
As an aside, you can use Form.recordError() as a convenience around
getDefaultTracker().getErrors().add().
HTH. Cheers,
lasitha.

Hi all,
I am trying to understand how to implement custom validation of form
fields.
Here's what I've got so far:
CreateAccount.java:
public class CreateAccount {
@InjectComponent
private Form createAccountForm;
@OnEvent(value = "validate", component = "createAccountForm")
void validate() throws ValidationException {
log.debug("validate");
if (password == null || !password.equals(password2)) {
createAccountForm.getDefaultTracker().getErrors().add("passwords
don't match");
}
}
}
and CreateAccount.html:
<t:form t:id="createAccountForm">
<t:errors/>
<t:passwordfield t:id="password" t:validate="required,minLength=4"/>
<t:passwordfield t:id="password2" t:validate="required"/>
... etc
This is failing because Tapestry is trying to cast CreateAccount to
Form...
but why? Am I going about this all wrong? What am I missing here?
I feel a bit like I am stumbling around in the dark. Does anybody know
of
some T5 examples I can look at, just to get me going?
tia,
Marc
