MinimumValidator and Long problem
I have TextField that should take Long value, but on submit it does not
really work...
org.apache.wicket.RequestCycle logRuntimeException: Exception
'java.lang.ClassCastException: java.lang.Integer cannot be cast to
java.lang.Long' occurred during validation
org.apache.wicket.validation.validator.MinimumValidator on component
10:workForm:hire_worker_1
org.apache.wicket.WicketRuntimeException: Exception
'java.lang.ClassCastException: java.lang.Integer cannot be cast to
java.lang.Long' occurred during validation
org.apache.wicket.validation.validator.MinimumValidator on component
10:workForm:hire_worker_1
My code looks like that:
public Work() {
add(new FeedbackPanel("errorMsg"));
Form<String> workForm = new Form<String>("workForm", new Model<String>())
{
private TextField<Long> hire_worker_1 = new
TextField<Long>("hire_worker_1", new Model<Long>());
...
{
...
add(hire_worker_1.add(new MinimumValidator(0))
.setType(Long.class));
...
}
@Override
public void onSubmit() {
long hiring_worker_1 = hire_worker_1.getModelObject();
...
}
};
add(workForm);
}
Eclipse does like "new MinimumValidator<Long>(0)", so what's the solution
for my problem?

I have nothing else really, just same more of same stuff, only a Form with
Labels, TextFields and submit method.
Anyway, deprecated NumberValidator.minimum(0) method works without any
problems, are there any disadvantages of using that?

To me, putting code outside a method *is* a syntax problem, typically caused
by inexperience with anonymous inner classes, leading to not enough, or too
many }

its not a syntax problem. you cant have code outside a method unless
its in a static {} block.

Seems like you have a syntax error.... perhaps a problem with an anonymous
inner class. You can use Pastebin to paste entire file and we can attempt

Changing it to :
private TextField<Long> hire_worker_1 = new TextField<Long>("hire_worker_1",
new Model<Long>());
{
hire_worker_1.setType(Long.class);
}
Does not change anything. And is it normal that Eclipse does not let me add
anything without enclosing in { }?
BTW, is there any easy way to convert nulls to 0 when you submit empty
TextFields?

Re: MinimumValidator and Long problem

Since your model doesn't actually know what type of field it is operating on
(like PropertyModel does), you need to call setType(Long.class) on your text
field.
