The user guide mentions how to do it.
http://jakarta.apache.org/tapestry/UsersGuide/validation.html
Basically don't use ValidField for T4.
Now all the normal form components have built in validators i.e. TextField,
PropertySelection, Checkbox, etc.
<component id="someField" type="TextField">
<binding name="value" value="fieldValue"/>
<binding name="validators" value="validators:required,email"/>
<binding name="displayName" value="literal:some field"/>
</component>
If you have old T3 beans or custom ones you can use
<binding name="validators" value="validators:$beanName"/>
Which is mentioned very briefly in the docs.

Subject: TextField validators?
I'm trying to setup some validators in a small test application I'm
writing.
I have to say that as a newcomer the tapestry documentation leaves a lot
to
be desired. There seems to be a lot of conflicting information as parts
are
updated for 4.0 and other parts aren't. But on to my specific question...
This is an excerpt from the TextField component reference:
A TextField may be decorated by the Form's validation delegate, but does
not
have a validator, so is limited in editting properties types beyond
string.
In most cases, the ValidField component is preferred.
And this is an excerpt from the ValidField component:
Warning
This component has been deprecated; Tapestry 4.0 adds even better support
for validation to TextField, TextArea and most other form element
component.
And there's even a link to the TextField reference page in the warning.
Is
there some documentation somewhere that describes how to do TextField
validation using the 4.0 "better support for validation". Or am I looking
at the wrong reference?
Any help would be appreciated.
Thanks,
Adrian
