Re: Ajax validating individual form fields
Just a little update, I managed to get the form level validator working by
doing what you said, basically creating a validator that takes a component
as an argument, and compares the ivalidatable.value against the model
object:
protected void onValidate(IValidatable validatable) {
if(!validatable.getValue().toString().equals(component.getModelObjectAsString()))
error(validatable);
}
Unfortunately the getResetPassword is a final method for some reason, so I
was not able to override it as I hoped. Instead I did this on the ajaxbutton
used to submit the form:
protected void onAfterRender() {
super.onAfterRender();
pass.setResetPassword(false);
}
protected void onBeforeRender() {
super.onBeforeRender();
pass.setResetPassword(true);
}
And that seemed to work for the password fields. Thanks for your help!

If so I'm not sure if it would be possible to fire a form level validator on the onblur of the second component without submitting the entire form. I think you are correct. Maybe it is an option to write a custom validator that compares the two fields, and attach that to the second field. The error can then be shown at the second field. Another issue I thought of is if you use a password text field you wouldn't be able to use AjaxFormComponentUpdatingBehavior because even if the input is valid it would erase immediately. Maybe there is a clever way to override the isPasswordReset so that it only is true when the form is submit through a button and not that behavior? I have no idea, but am curious to see your solution :-). Regards, Daan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Ajax validating individual form fields
Hi fatefree, Check this blog post: http://stuq.nl/weblog/2008-09-03/user-friendly-form-validation-with-wicket I think this achieves what you want.

What I have tried is using the AjaxFormValidatingBehavior.addToAllFormComponents(form, "onblur"), but as you probably know this causes the entire form to be validated on the onblur which is both confusing to a user who hasnt been able to put all values in, and also seems to be excessive load as id rather the rest of the form be ignored.
