Re: How to determine which validator failed in a CompoundValidator?
Hi,
I think you have to be sure that you do not send an unencrypted
password across the wire...
That said, I think you can post back the value to the server and
update the PasswordStrengthMeter with that.
Or you could use Javascript to make it all client-side.
It all depends on implementation if you could reuse classes from my
blog post.
I think you can use standard Ajax behaviors to update the
PasswordStrengthMeter. After that, you could use standard form
validation to validate the strength of the password. With my code, you
can display an error next to the password field and highlight it.

Daan,
Yes, this definitely looks like the direction I should go for most of
my form components. Thanks for sharing it!
However, I also need to make a PasswordStrengthMeter, which will show
different values (and css styling) based on the strength of a password
entered into a password field. Something like one of these:

Before I embark on building it, do you have any suggestions on easy
ways to use your solution to do this?
Thanks!

Actually, I want just one error message right next to the

that is specific to the username. I also want to highlight via
css the

as well,
wouldn't it?

How to determine which validator failed in a CompoundValidator?
On a site registration form, I have three validators on the username
field. One tests to make sure the username is at least 3 characters
long, another one checks to make sure it uses valid characters, and
the last one checks if the username is already taken. This all works
fine.
Now I'm working on adding an ajax behavior to the field so that as the
user types, validation happens in real time. There is a label called
"valid" that should change to contain on of the following messages, as
appropriate based on the success/failure of the validation:
You have entered a username that is too short.
You have entered a username with invalid characters.
You have entered a username that is already taken.
Your username is available!
The problem is, I don't know how to determine which of the validators
in the CompoundValidator have failed. Is this possible to determine?
How should my AjaxUsernameBehavior know which message to display?
Here is some preliminary code:
RequiredTextField userName = new
RequiredTextField("username",new PropertyModel(user,"username"));
CompoundValidator validators = new CompoundValidator();
validators.add(StringValidator.minimumLength(3));
validators.add(new
PatternValidator("[_A-Za-z0-9-]*",Pattern.CASE_INSENSITIVE));
validators.add(new UsernameValidator());
userName.add(validators);
AjaxFormComponentUpdatingBehavior usernameBehavior = new
AjaxUsernameBehavior("onkeyup", validators, valid);
usernameBehavior.setThrottleDelay(Duration.ONE_SECOND);
userName.add(usernameBehavior);
add(userName);
Label valid = new Label("valid","");
valid.setOutputMarkupId(true);
add(valid);
I haven't implemented AjaxUsernameBehavior yet, thus no code. But I'm
thinking I'll need to provide it with the validators and the component
to update ("valid").
Thanks in advance for any ideas!
