[jira] Commented: (BEANUTILS-353) Unable to call isUseDefault() to check whether a default value will be returned

Franklin Phan commented on BEANUTILS-353:
-----------------------------------------

Even calling a getter here is unsafe?
My intention was to have a way of checking before unnecessarily instantiating 
and registering a SqlTimestampConverter that returns default NULL every time:

Converter converter = 
BeanUtilsBean.getInstance().getConvertUtils().lookup(java.sql.Timestamp.class);
if (!converter.isUseDefault()) { // But unfortunately, this check is invalid!
    BeanUtilsBean.getInstance().getConvertUtils().register(new 
SqlTimestampConverter(null), java.sql.Timestamp.class);
}

>          Components: ConvertUtils & Converters
>    Affects Versions: 1.8.0

> One can never call isUseDefault() to check on a Converter given the way you 
> have ConverterFacade designed and in ConvertUtilsBean:
> {{
>     private void register(Class clazz, Converter converter) {
>         register(new ConverterFacade(converter), clazz);
>     }
> }}
