T5 form field validation, component injection

[Marc A. Donis]

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
