[Tapestry-developer] Unable to validate Forms

[Luis Neves]

Did something drastic chaged between 2.1 and 2.2 in the way Tapestry does
form
validation?

I'm banging my head against the wall with this one. Is it
now necessary to have a Shell component on a page to make
the validation work? It wasn't necessary before.

I send 3 files in attachement (EditAccount.page,
EditAccount.html and EditAccount.java). Can someone tell me
what I'm doing wrong?

Thanks in advance,

Luis Neves
