Validate, Navigate Wizards
Hi,
when I validate the data of a WizardStep after pressing Next, I
navigate within the validate method to the WizardStep.previous()
step in the false case.
Works fine! But calling the method WizardStep.previous() works
not for the first Wizard step. That's ok, there is no previous
one.
But how can I do it right?
Is there in general a way to navigate programmatically the
wizards? Depending to the user input the order of the wizards is
different.
Is it possible to override any method before a Wizard Step is
called on the client. What I found was a onNext() Method. But
this method is not existing anymore in the v1.4.
best regards
- jk

Hi,
sometimes the world is easy! Thanks for your support. Thinking in Wicket
means, to think easier :-D
For other readers, to get the right "required" validation message at the
feebackPanel an entry has to written into the Wizard's property file.
e.g. group.Required=My message on the feebackpanel...
So, the thread could be closed :clap:

Hi
If you only want to require that a radio button is selected, then
myRadioGroup.setRequired(true) already does that job. No need to
implement a custom form validator then.
BTW: RequiredTextField is nothing other than a TextField which calls
setRequired(true) in the constructor.. It's only here for convenience
since it is used very often.
so, .setRequired(true) is your friend as long as you only want to
check if a radio button has been selected.

Re: Validate, Navigate Wizards

Hi,
my intention is to check if special mandatory fields are filled.
What I found in the examples is the RequiredTextField... within the Wicket
lib.
I use a RadioBtnGroup with RadioBtn's, the user has to select one!
Thats all what I validate.
But no matter, with your hint I can solve that problem. Maybe I implement an
own RadioBtnGroup-Komponent who can check this in general, like the
RequiredTextField... :-)

Hi
Just one note - I just had another look at our FormValidator class - you
might wonder why you won't find the method error (FormComponent fc,
String resourceKey) provided in my example. The reason is, we wrapped
this to provide a direct access to localized error messages in our
custom FormValidator:
/**
* Reports an error against the validatable using the given literal
resource key. This means, no
* class prefix is prepended to the resource key.
*
* @param fc form component against which the error is reported
* @param resourceKey The resource key to use
*/
@Override
public void error (FormComponent fc, String resourceKey) {
fc.error(fc.getLocalizer().getString(resourceKey, fc));
}
Just calling error (Serializable message) inside your form validator
implementation will of course report the error against the FormValidator
and not the failing component.
So make sure you call myTextFieldThatFailed.error(...) instead of
error(...)
The Wizard will later test, if all contained components were successful
and only advance if none of them had its FormComponent.error() method
invoked.
Good luck
Matt

Hi Matthias,
thanks! I used error(), but the wizard didn't stop. I will check it, maybe I
use a ref-Object to call error().

Hi
Not sure why you even want to call next or previous at all manually?
I'm using 1.3.5 so that may make a difference but we're just adding
validators to the WizardStep which takes care of everything. We never
have to manually call previous() or next() ?
We're just doing:
add(new FormValidator() {
public FormComponent[] getDependentFormComponents() {
return new FormComponent[] { radioGroup, checkbox };
}
public void validate (Form form) {
if (isSelected(radioGroup, radio1)) {
if (isChecked(checkbox)) {
error(checkbox, "our.error");
}
}
}
});
Note that FormValidator is our implementation of AbstractFormValidator
which is just there to provide some helper methods like the isSelected()
and isChecked() plus some optimizations.
Now when the error() is called, the wizard won't go to the next step.
