Re: [t5] Validator question
Not possible?
Sometimes a validator needs to look at input from another field to see
if it is valid (ie password/confirmPassword). I know it's easy to do
in onValidateForm, but I'd like to see how to do it in a nice modular
Validator. I'm looking for something like:
public void validate(Field field, String sourceFieldId,
MessageFormatter formatter, Object value) throws ValidationException {
Component page = ((AbstractField) field)._resources.getPage();
try {
Method getter =
page.getClass().getDeclaredMethod(getMethodName(sourceFieldId));
String sourceValue = (String) getter.invoke(page);
if (value == null || !value.toString().equals(sourceValue))
throw new ValidationException(buildMessage(formatter,
field));
} catch (Exception e) {
log.error(No public getter field in page for: +
sourceFieldId);
}
}
but can't do that (the only problem being the private _resources). How
can that be done in a Validator? I can't inject anything. I don't
actually need to make my own field which exposes the
ComponentResources, do I?
Thanks.

Re: [t5] Validator question
Sorry, those APIs are not in place yet. I have JIRA issue add
optional validators, which is a loose, general term for what you are
aiming for (password is required if userName is given).
I think some relationships may not be expressable using the @Validate
annotation, i.e., the string representation; I'm thinking there will
be a kind of JavaScript template object that will be used to generate
some kinds of JavaScript.
Things have slowed down on 5.0 for a moment, while I work on an urgent
client project (in Tapestry 5).

Re: [t5] Validator question
Ok no worries.
On a related note, where do you put the messages file for a custom
validator? In the example below, which looks for a key called
'confirm', I have tried Confirm.properties (in same package as
validator called Confirm.java), Signup.properties (the page using the
validator) and app.properties. The latter two of course have
verifiably working messages. I always get a [[missing key: confirm]]
though.
Back to my validator question, I couldn't find the JIRA issue you were
referring to.
BTW, the client side of this type of a validator works quite nicely.
In .java:
@Validate(required)
public String getPassword() {
return password;
}
@Validate(required,confirm=password)
public String getConfirmPassword() {
return confirmPassword;
}
On the .tml:
script
Object.extend(Tapestry.Validator, {
confirm: function(field, message, constraint) {
Tapestry.addValidator(field, true, function(value, event)
{
var confirmationSourceField = $(constraint);
if (confirmationSourceField == null) {
console.error(No such field: + constraint);
return;
} else if (value != confirmationSourceField.value) {
event.recordError(message);
}
});
}
})
/script
And in Confirm.java (the validator):
public void render(Field field, String sourceFieldId,
MessageFormatter formatter, MarkupWriter markupWriter, FormSupport
formSupport) {
formSupport.addValidation(field, confirm,
buildMessage(formatter, field), sourceFieldId);
}

Re: [t5] Validator question
Actually, I was able to get this done.
I had to contributeValidationMessagesSource to get the messages.
And to get to the current page component from within the Validator, I
was able to do this:
public static void contributeFieldValidatorSource
(MappedConfigurationString, Validator configuration,
@InjectService
(ComponentSource)ComponentSource componentSource,
@InjectService
(Request)Request request
) {
configuration.add(confirm, new Confirm(componentSource,
request));
}
and then:
String[] pathComponents = request.getPath().split(/);
String pageComponent = pathComponents[pathComponents.length
- 1];
String[] pageComponents = pageComponent.split(\\.);
Component page = componentSource.getPage(pageComponents[0]);
but this seems a little fragile. Is there a better way?
I do see what you mean though - there is nowhere to attach a piece of
javascript to accompany this validator, so it just goes into my own
global library. But I'm pretty happy overall with this solution.

Re: T5 validator question
I've already found my answer in the magical @Inject private FieldValidatorSource _fieldValidatorSource; with the _fieldValidatorSource.createValidator(this, myRegistredValidator, null); everything works fine ! Bye -Rick Riccardo Ruffilli wrote: Hi All, I'm working on validator class in my t5 application, and I've defined my own validator that implements ValidatorVoid, Object I've registred them like t5 contribution in my AppModule.java and then I can use them easily in my tag with the parameter validator=validate:myownvalidator. With the validate prefix I've noticed that t5 obtain a FieldValidatorImpl that contains myvalidator instance like _validate internal property. I'd like to modelize my component to make it working without any template explicit parameter using a model class that wrap all my tag parameter in that way t:mycomponent t:mymodel=prop:componentModel / instead of t:mycomponent t:par1=prop:par1Value t:par2=prop:par2Value / and at rendering time My component get all that values from the model specified. That works fine exept for validator parameter because I need to obtain myown FieldValidatorImpl instance. Any ideas about that ?
