I have an attribute that is using the javaEnum prototype. This works awesome - until some value comes trouncing through from the source DB (not under my control) that is, in some circumstances an empty string instead of one of the enum values. This yields an
error like this which is understandable:
IllegalArgumentException: No enum constant edu.ucla.gseis.core.enums.PaySchedule.
at java.lang.Enum.valueOf(Enum.java:238)
at edu.ucla.gseis.core.enums.PaySchedule.valueOf(PaySchedule.java:1)
So, I tried to change the factory method (from ‘valueOf') in the model to use my custom fromString method in my enum. The method should call valueOf just like the original factory method.
public PaySchedule fromString(String
aString) {
if (S.isEmpty(aString)) {
log.info("trying to convert the value of an empty string to PaySchedule. Switching to UN forced."
);
return valueOf("UN");
}
return valueOf(aString);
}
However, now I get a new error like below. Notice this is happening when fetching EO’s that use this attribute. Does anyone have some kung-fu to help me here? Or do I have to abandon use of the javaEnum
prototype here?
