tapestry 4 validators

hello,

Why can't I use this code?

    <bean name="basicValidator"
class="org.apache.tapestry.valid.StringValidator">
        <set name="required" value="true"/>
        <set name="minimumLength" value="1"/>
    </bean>

    <component id="firstNameField" type="TextField">
        <binding name="value" value="ognl:firstName"/>
        <binding name="validators" value="bean:basicValidator"/>
    </component>

I know, that I can use value="validators:required,minLength=0", but I
don't understand why there is java.lang.ClassCastException on
org.apache.tapestry.form.ValidatableFieldSupportImpl.validate(ValidatableFieldSupportImpl.java:89)

thanks, miso

Hello,

I suppose StringValidator is used only with ValidField, because it 
implements IValidator interface. With text field you can use validators 
which implement Validator interface.
