There is a short article in the wiki that shows how to
create your own
validator.
http://wiki.apache.org/jakarta-tapestry/HowTos
You need something like the following.
public class IntegerValidator extends BaseValidator {
public void validate(IFormComponent form,
ValidationMessages messages, Object obj)
throws ValidatorException {
String input = (String)obj;
try {
Integer.parseInt(input.trim());
}
catch (NumberFormatException nfe){
throw new ValidatorException(getMessage());
}
}
}
Add the following to hivemodule.xml :
<contribution
configuration-id="tapestry.form.validator.Validators">
<validator name="integer" configurable="true"
class="math.validators.IntegerValidator"/>
</contribution>
In your .page :
<bean name="integerValidator"
class="math.validators.IntegerValidator">
<set name="message" value="literal:Preference
must be an integer"/>
</bean>
<binding name="validators"
value="validators:$integerValidator"/>
