How to invoke tapestry client side validation on one fields?

[Yohan Yudanara]

Hi,

I want to ask a question:

Client side validation by default works on "blur" event, but I've change
the form property using clientValidation="submit", so that client side
validation only triggered on submit.
However, I want to trigger client side validation on one particular field
to works on "blur" event.
Is it possible to do that?

Let's say I have this code:
this.accountInput = $("fieldNeedOnBlurValidation");
Event.observe(this.accountInput, 'blur', ???? <-- what should I put here to
trigger client-side validation only on this field?);

Thanks in advance..
