Apologies for reviving a dead thread, but I'm having the issues
discussed below and don't entirely understand the proposed
solutions. In my case I have a form with multiple TextFields each of
which is required. Using the common suggestion of:
AjaxFormValidatingBehavior.addToAllFormComponents(form,"onblur");
The user is prompted with multiple required field errors when they
tab out of the first required field. This obviously isn't ideal as
the user hasn't even had a chance to enter data in the other fields.
This even happens using the form validation example straight out of
the "Pro Wicket" book.
I've got an AjaxFallbackButton mostly working to validate everything
only when the form is submitted, but if the user gets an error and
then submits the form again without fixing the error the form is
submitted without validation. I'm sure there is a bug in my code
somewhere, but even if there is do I really need to write a half page
of code to implement an AjaxFallbackButton for what would seem to be
the most common use case (wanting to validate the entire form at once
prior to submission)?
I just feel like I'm missing the obvious one liner that will do this
for me. Can someone please point me to an example of validating
multiple form fields using Ajax and wicket upon form submission?
Thanks,
-Mike

I worked it out. Very simple solution!
On the AjaxSubmitLink override the onError method and add the
feedback
panel to the AjaxRequestTarget !

Yes, that or setDefaultFormProcessing(false) as Eelco suggested
before.
That's not doing validation by hand, just postponing the moment of
validation to fit your needs. Then, when validation should be done,
call
process() on the form and that will carry on validation and model
updating
as usual. It's as simple as that.

have you tried AjaxFormComponentUpdatingBehavior?

Thanks but this does not solve my problem.
I am submitting the form via ajax using an AjaxSubmitLink. If the
form
has
errors on it then I do not get the submit, if the form has no errors
then
the submit code runs ok. The errors are not displayed.
If I add a AjaxFormValidatingBehavior for the onblur event then I
can
see
the errors but they check for required fields etc as soon as the
first
field
is left therefore displaying errors too soon.
With the AjaxFormValidatingBehavior set to onsubmit event I get
no error
reporting and no submit.
I need to validate the entire form only when submit button is
pressed
pressed. One possibility is to do the validation "by hand" in the
submit
processing code.

concerning "one field depends on another":
have you already taken a look at
http://cwiki.apache.org/confluence/display/WICKET/Validating
+related+fields
?
the code is still 1.2, but it should get you started.

Hi
I have a form that is submitted by ajax.
I have validation on fields of the form.
Using AjaxFormValidatingBehavior the form will be validated and
error
messages displayed when the onblur event is used.
However this is not what I need as the validation of one field
depends
on
another. I have tried to set the AjaxFormValidatingBehavior to
onsubmit
but
it appears that if the form is invalid then its not submitted so no
errors
are displayed.
Is there any way I can validate my form using ajax only when it is
submited ?
