Oups sorry, I haven't seen something in your previous mail,
It didn't work for the following reason:
the validators binding only accept a collection of Validators that
are new to tap4.
Thus you can only use the validators prefix
(validators="validators:required, pattern=myPattern") etc...
The approach you were taking is only available for ValidField (which
was for tap3, and is still available for backward compatibility). As
from tap4, you souldn't be using
ValidField and Validator, But the new validation mechanism TextField
validators="validators:required, min=0". With this new system every
field is valid-able now.
If you want to provide a validator configuration in the page spec
(.page) you can do the following:
<bean name="emailValidator"
class="org.apache.tapestry.form.validator.Pattern"> <-- New type of
validators as of Tap4
<set name="pattern" value="[A-z]+">
</bean>
and the use
<binding name="validators" value="validators:required,
$emailValidator"/> <-- Look at the dollar sign

Thanks for your reply. Sorry to tell you that the
method suggested seems not work, same error message
resulted. Finally solved by using validators but I
still willing to know what’s the root cause and the
expression posted previous cannot apply to validators.
I need to changes as follows, any thought? Thanks.
component id="_textField_email" type="TextField">
binding name="value" value="ognl:email"/>
binding name="validators"
value="validators:[EMAIL PROTECTED]"/>
binding name="displayName"
value="message:label_email"/>
/component>
One more thing, is it possible to customize the error
message by our own when using validators? Thanks in
advaned

Try to put literal in front of your pattern.
Thus :

Dear all
I have some problem on Pattern Validator. Similar
code
work fine in Tapestry 3 but have problem on
Tapestry
4. Keep saying that "Error initializing property
patternString of bean 'emailValidator'" and I
cannot
figure out what's the problem.
Coding as below
bean name="emailValidator"
class="org.apache.tapestry.valid.PatternValidator"
lifecycle="page">
set name="patternString"
value="[EMAIL PROTECTED],6}$"/>
set name="patternNotMatchedMessage"
value="invalid-email-format"/>
set name="requiredMessage"
value="field-required"/>
/bean>
component id="_textField_email" type="TextField">
binding name="value" value="email"/>
binding name="validators"
value="beans.emailValidator"/>
binding name="displayName"
value="literal:label_email"/>
/component>
Any hints would be appreciated. One more question
on
i18n, does the error message support different
languages? Thanks a lot.
regards
wayne
