I have created a custom converter to convert a String back into a Date.
public Object convert(Object fromObject){
if (fromObject != null && fromObject.toString().trim().length() == 0){
return null;
}
for (DateFormat f : formats){
try{
return f.parse(fromObject.toString());
}catch (ParseException e){
// Ignore
}
}
throw new RuntimeException(message);
}
Basically, if the string is not parsable a RuntimeException will be thrown.
I have added the converter to the update strategy in the data-dinding and it is being called.
The issue is when the exception is thrown. (For example when i start to type the date in the TextFiled). Instead of appearing the decorator field to indicated an error in the input, the exception is not catch.
The exception appears in the console log (The error in the logs is at the end of the question) as it seems that nobody is catching it.
What i am missing? The exception in the converter should be catch within the updateStrategy and display the error, shouldn't it?
