Thank you Thomas for the prompt response and a nice example.
Does anyone know why there are 2 types of BaseValidators?
org.apache.tapestry.form.validator.BaseValidator
org.apache.tapestry.valid.BaseValidator
Took me an hour figure out why I get ClassCastExceptions thrown ;)
I noticed some validators were created by Howard since 4.0 and others
were created by contributors from previous versions of tapestry. Are we
trying to phase out org.apache.tapestry.valid package?

For a text field where we only wanted a certain set of ascii characters

component & validator pair...
<component id="filedByField" type="TextField">

<binding name="validators" value="bean:asciiValidatorReq"/>
<binding name="displayName" value="literal:Filed By"/>
</component>

Subject: pattern validator
I'm trying to use the pattern validator in my .page to do some input
validation. I was thinking I could use regular expressions just like in
Perl. Similar to the following:
<binding name="validators"
value="validators:required,pattern=[a-zA-Z]+"/>
Tried googling, no luck. Could someone please provide a simple example?
Thanks guys,
Dennis
