---------------------------------------
Summary: NumberTextField does not have default minimum and maximum
Key: WICKET-4584
URL: https://issues.apache.org/jira/browse/WICKET-4584
Project: Wicket
Issue Type: Bug
Components: wicket
Affects Versions: 1.5.6
Reporter: Adam Pierzchała
Javadoc of NumberTextField says:
A TextField for HTML5 <input> with type number.
Automatically validates the input against the configured min and max
attributes. If any of them is null then Double.MIN_VALUE and Double.MAX_VALUE
are used respectfully. Note: FormComponent.setType(Class) must be called
explicitly!
It is not true. We have constructor which sets them to null:
public NumberTextField(String id, IModel<N> model, Class<N> type)
{
super(id, model, type);
validator = null;
minimum = null;
maximum = null;
}
and if I don't set them manually, in case of error nulls go to RangeValidator
(line 84-85:
error.setVariable("minimum", min);
error.setVariable("maximum", max);
causing:
java.lang.IllegalArgumentException: Argument 'value' may not be null.
Nevertheless, I think reflection API should be used to determine if given
Number has MAX_VALUE/MIN_VALUE and this one should be used. In other case I
think it is ok to use Double.MAX_VALUE/MIN_VALUE.
or maybe you have another ideas?
