Re: Correct use of RangeValidator
If you are using a map TextField can't determine the type. -Matej On Tue, Mar 17, 2009 at 9:27 PM, Igor Vaynberg wrote: > if you use a propertymodel alongside a formcomponent then yes, but it > is not the generic you declare that is used, it is the model > performing a runtime reflection check on the type of getter/field it > is using. > > -igor > > On Tue, Mar 17, 2009 at 12:08 PM, Adriano dos Santos Fernandes > wrote: >> Igor Vaynberg escreveu: >>> >>> textfield doesnt know that it has been declared as textfield >>> at runtime unless it is an anonymous class. welcome to java generics. >>> lookup type erasure. >> >> Hmm...

Re: Correct use of RangeValidator
if you use a propertymodel alongside a formcomponent then yes, but it is not the generic you declare that is used, it is the model performing a runtime reflection check on the type of getter/field it is using. -igor On Tue, Mar 17, 2009 at 12:08 PM, Adriano dos Santos Fernandes wrote: > Igor Vaynberg escreveu: >> >> textfield doesnt know that it has been declared as textfield >> at runtime unless it is an anonymous class. welcome to java generics. >> lookup type erasure. > > Hmm...

textfield doesnt know that it has been declared as textfield
at runtime unless it is an anonymous class. welcome to java generics.
lookup type erasure.

Re: Correct use of RangeValidator
I thought that I was telling the TextField, by the type , that
it's model object is an integer. And I thought that it would retrieve
its value from the model I set on it's form.
super(name, new CompoundPropertyModel(valueMap)
valueMap is an existing ValueMap with a value with key "intField" and
that ValueMap#getAsInteger("intField") would be called. I guess
ValueMap#getString("intField") is being called. Is it the ValueMap that
is messing me up? What am I missing?

According to the error message, the validator gets a String value here;
have you checked the actual IModel used by the field? The default Model
for *TextField uses String IIRC...
IModel model = new PropertyModel(theBean, "intField");
RequiredTextField intField = new
RequiredTextField("intField", model);

Correct use of RangeValidator
I am getting a ClassCastException when using RangeValidator like this:
RequiredTextField intField = new
RequiredTextField("intField");
intField.add(new RangeValidator(0, 100));
or like this:
RequiredTextField intField = new
RequiredTextField("intField");
intField.add(new RangeValidator(0, 100));
WicketMessage: Exception 'java.lang.ClassCastException:
java.lang.Integer' occurred during validation
org.apache.wicket.validation.validator.RangeValidator on component
2:body:recvAnalisysForm:intField Root
cause:java.lang.ClassCastException: java.lang.Integer at
java.lang.String.compareTo(String.java:90)
The example app shows it coded this way, but NumberValidator has been
deprecated.
add(new
RequiredTextField("integerInRangeProperty").add(NumberValidator.range(0,
100)));
What is the correct way of using RangeValidator and how do you type it?
