Validator class cast exception wicket 1.3.5
Hello,I have a converter which I can verify is being called, but when the
validator is being called it is not being called on the String value but the
object which causes a ClassCastException.
Here is my converter:
@Override
protected IConverterLocator newConverterLocator() {
ConverterLocator locator = new ConverterLocator();
locator.set(types.thing.wc.microsoft.com.CodableValue.class, newIConverter() {
public Object convertToObject(String arg0, Locale arg1) {
types.thing.wc.microsoft.com.CodableValue cv =
newtypes.thing.wc.microsoft.com.CodableValue();
cv.setText(arg0);
return cv;
}
public String convertToString(Object arg0, Locale arg1) {
return ((types.thing.wc.microsoft.com.CodableValue) arg0).getText();
}
});
return locator;
}
Here is my form:
TextField treatment = new TextField("treatment", new PropertyModel(allergy,
"treatment"));
treatment.setType(CodableValue.class);
treatment.add(StringValidator.lengthBetween(2, 200));
add(treatment);
Here is the error:
org.apache.wicket.WicketRuntimeException: Exception
'java.lang.ClassCastException: types.thing.wc.microsoft.com.CodableValue'
occurred during validation
org.apache.wicket.validation.validator.StringValidator$LengthBetweenValidator

Re: Validator class cast exception wicket 1.3.5
Hi Igor,
I'm a little confused. I attached a StringValidator - shouldn't that work
on a String? Also I assumed Validators work on the values of form fields
after converted to String?Thanks,

Re: Validator class cast exception wicket 1.3.5
no, validators work on a converted type - same type as the model object
notice your converter is converting the value to a codablevalue type -
that is the object that the validators will work on - they validate
the same object that will be put into the model if validation passes.
it looks like in your case your validation is a conversion-related
validation so that check should go into your converter - the
converttoobject() method - you can throw ConversionException and set
the appropriate error message on it.

Hi Igor,
I'm a little confused. I attached a StringValidator - shouldn't that work
on a String?

Hello,I have a converter which I can verify is being called, but when the
validator is being called it is not being called on the String value but the
object which causes a ClassCastException.
Here is my converter:

ConverterLocator locator = new ConverterLocator();
locator.set(types.thing.wc.microsoft.com.CodableValue.class, new IConverter()
{

cv.setText(arg0);
return cv;
}
public String convertToString(Object arg0, Locale arg1) {
return ((types.thing.wc.microsoft.com.CodableValue) arg0).getText();
}
});
return locator;
}
Here is my form:
TextField treatment = new TextField("treatment", new PropertyModel(allergy,
"treatment"));
treatment.setType(CodableValue.class);
treatment.add(StringValidator.lengthBetween(2, 200));
