Simple question from tapestry novice
Hi !!
I have textbox and button on a page.
I need the button to be disabled when in text field we have less then 3
characters entered.
Normally I would do this with JavaScript.
How to proceed with such simple case in Tapestry application?
Java Script or the power of TapestryMagic?
Best Regards
-jbo

Q1 and Q2: Do the validation in your listener method, after
delegate.getHasErrors(). Here is an example:
public void addUser(IRequestCycle cycle)
{
IValidationDelegate delegate = (IValidationDelegate) getBeans().getBean(
"delegate");
if (delegate.getHasErrors())
return;
String password1 = getPassword1();
String password2 = getPassword2();
if (!password1.equals(password2))
{
IFormComponent pwd1 = (IFormComponent) getComponent("inputPassword1");
delegate.setFormComponent(pwd1);
delegate.recordFieldInputValue("");
delegate.record(getMessage("passwordMismatch"),
ValidationConstraint.CONSISTENCY);
setPassword2(null);
return;
}
...
}

Best Practises, Validation, I18N
Posted by Manri Offermann <ta...@eastbeam.co.jp>.
Hi all,
sorry I am still new here and I have multiple questions ...
Q1
Is there any way of validating values of two different form components with
the ValidationDelegate and a custom Validator? For example:
- Password & Password Confirmation (whether the values of both fields are
identical)
- Email & Email Confirmation (whether the values of both fields are
identical)
If not, what is the best practise to do validations like these?
Currently I check both strings and then record a new ValidatorException to
the Delegate.
Q2
How about other errors which are raised from somewhere else, like a "Login
failed" error? Is it bad practise to record them with the ValidationDelegate
since the ValidationDelegate should only record Form Validation errors?
Q3
Where is the best place to store String properties like "Application Name"?
In a multilingual environment the application name is not always identical
(different alphabets, names -> can not store in application specification)
and String properties like these are needed by several pages and
components - so a per component or page solution is not very comfortable. I
am currently loading a ResourceBundle in the Global object - how is everyone
else solving this matter?
I have just started with Tapestry+Spring+Hibernate. Great Tools! - Except
for the ugly URLs ... But I have followed the instruction in the Wiki for
Friendlier URLs and it works.

Hi,
The behaviour you describe is purely on the client/browser side. You'll
still need to do this with Javascript.
