I have the jsf input text as double type in pojo class.
i want to validate that field with empty check.by default in page load the value comes as 0.0 in the text field.once i clear the value(i.e empty value) and click submit button, the text field is not getting validated.
任何幫助,將不勝感激。如何驗證jsf中雙精度型的空值?
