The magic is calling setVariable on the ConversionException. Thanks to Igor's
new book <https://www.packtpub.com/apache-wicket-cookbook/book> for teaching
me that. ;)
So in your page's property file you'd have (you had the wrong case on
*IC*onverter
in your last email):
mortgageAmountPrimary.IConverter.Double=You must enter a valid value for
${user}'s mortgage amount field to continue with this application.
Java code:
form.add(new
TextField<Double>("mortgageAmountPrimary",Double.class){
@Override
public IConverter getConverter(Class<?> type)
{
return new DoubleConverter(){
@Override
public Double convertToObject(String value, Locale
locale)
{
try{
return super.convertToObject(value, locale);
}catch(ConversionException e){
* e.setVariable("user", "Theos");*
throw e;
}
}
};
}
});
I did it all inline so you could see it. But subclassing to make it more
useable, like getting the variable's value via a passed in Model wouldn't
hurt.
