Changing this:
Integer startNumber = (Integer) getFieldValue(_startFieldName, object);
if(startNumber == null)
addFieldError(_startFieldName, "Start Year is a required field.");
To this:
Integer startNumber = (Integer) getFieldValue(_startFieldName, object);
if(startNumber == null) {
setDefaultMessage("Start Year is a required field.");
addFieldError(_startFieldName, object);
}
Seems to solve the problem.
However, I did discover something strange. If a NPE is thrown in my
validator, the exception is swallowed. Any ideas on what could be causing
this. There's no information in my logs or shown in my browser (just
Tomcat's default 500 page).
