Apparently setType on a FormComponent (needed for NumberValidator) sets
the required flag for primitive types. With the required flag set a null
field never makes it to my validator.
Why does setType set the required flag for primitives?
/**

public final FormComponent setType(Class type)
{
this.typeName = type == null ? null : type.getName();
if (type != null && type.isPrimitive())
{
setRequired(true);
}
return this;
}
looks like a bug to me. im sure someone had something in mind though - a
weird thing to do. who committed that?

oh, i should mention that my wicket is not head. it was frozen a couple
weeks back, so it's possible this is a regression. you might want to look
at the revision history for the various classes involved in validation.

maybe this is a bug? i have a ConstrainedPropertyValidator which extends
AbstractValidator (which implements INullAcceptingValidator) and returns
true for validateOnNullValue() and it works just fine. you might need to
trace into the validation code to figure out why it's not calling your
validator.

Hi
How can I have a NumberValidator allow null values ? I tried extending
the DoubleRangeValidator, implement the INullAcceptingValidator
interface and returning true for validateOnNullValue but my Validator
still isn't called. Also not setting the required property on a
TextField won't give help, when going through the visitFormComponents
the FormComponent is still listed as not valid when no value is provided
in the form. Thanks.
gr,
Thies
