Re: FormValidators and messages property file
Hi Martin,
Thanks for your help. That worked but I had to do a few extra things such
as setting the values for '${label0}', etc. What I don't get is why do we
need to do this extra thing for Form validation classes (extending
AbstractFormValidator) but not for component validation classes
(implementing IValidator).
For others who may face the same problem, this is how got it working:
@Override
public void validate(Form<?> form)
{
Date fromDate = fromDateFormComponent.getConvertedInput();
Date toDate = toDateFormComponent.getConvertedInput();
if ( fromDate != null
&& toDate != null
&& fromDate.after(toDate))
{
ClassStringResourceLoader loader = new
ClassStringResourceLoader(FromDateBeforeToDate.class);
Application.get().getResourceSettings().getStringResourceLoaders().add(loader);
ValidationError error = new ValidationError();
error.addMessageKey(getClass().getSimpleName() + "." +
"fromDateAfterToDate");
error.setVariable("label0",
fromDateFormComponent.getLabel().getObject());
error.setVariable("label1", toDateFormComponent.getLabel().getObject());
fromDateFormComponent.newValidatable().error(error);
}
}
FromDateBeforeToDate.properties
FromDateBeforeToDate.fromDateAfterToDate=Invalid input: The '${label}' date
is after the '${label}' date
I thank you again for teh quick and helpful response.

Hi,
As I said the simplest is to just use form.error("the.key"):
@Override
public void validate(Form<?> form)
{
Date fromDate = fromDateFormComponent.getConvertedInput();
Date toDate = toDateFormComponent.getConvertedInput();
if ( fromDate != null
&& toDate != null
&& fromDate.after(toDate))
{
form.error(getClass().getSimpleName() + "." +
"fromDateAfterToDate");
}
}

Well, I wanted these to be independent validation classes. But now it seems
like a bad idea. I will make them part of the form.
Martin, your comments and help are much appreciated.
Thanks.

Hi,
I see what happens.
form.getString() would work because of
https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/resource/loader/ValidatorStringResourceLoader.java#L100
But using ValidationError has no reference to the form, and thus its form
validators, and it fails.

I hope this is not your real code for production.
This will add the loader to the list of loaders on every validation.
