I am thinking that you may need to: define a bean and it's
properties, then pass it to the validator parameter. You are right,
still, that tapestry 4 validators are confusing, even after reading
the java source.
Perhaps someone who has had success with multiple validators,
including custom validators, could elaborate on this issue.

Well, making that change gave another exception: "No validator named
'string' has been defined."
So, since the "string" validator was not defined I just left it with
"required" and it worked. I saw it work but I don't quite get it.
Please help me understand this:
The docs say that the proper way to use a validator is with the
syntax:
validator:name[,property[=value]]*
Which would make it valid for me to use:
validator:string,required
String, being the validator and "required" being one of the
validator's
properties.
If this has changed so that I must now use the prefix "validatorS"
and the
commas to separate between different validators, instead of different
properties for a single validator, how is it that I can pass along any
needed properties to a validator?
For example: If I have a validator called "MyValidator" and I want
to set
two properties in this validator (prop1 and prop2), how would I do
that?
I just noticed that all validators present in the Tapestry 4
framework take
only one property and the property always has the same name as the
validator
itself. Is that a new requirement?

You have to use validator-S- prefix when specifying multiple
validators.
validators="validators:string,required"

I'm trying to perform input validation in Tapestry 4.
I have the following input field:
<input jwcid="[EMAIL PROTECTED]" size="15" maxlength="50"
displayName="message:class-name"
validators="validator:string,required"
value="ognl:productClass.name"/>
And when I submit the form I get this:
java.lang.ClassCastException:
org.apache.tapestry.valid.StringValidator
org.apache.tapestry.form.ValidatableFieldSupportImpl.validate
(ValidatableFie
ldSupportImpl.java:89)
$ValidatableFieldSupport_105ef3b5a9e.validate

(TextField.java:86)
org.apache.tapestry.form.AbstractFormComponent.renderComponent
(AbstractFormC

...
A peek at the code and I find that StringValidator is an
"IValidator" type
and it's being typecast into a "Validator".
Am I using this in a wrong way or could this be a bug? I'm using
Tapestry4-beta4.
Thanks,
