Hi Chuck,
After digging and stepping into the debugger, I figured out that the problem
come in the globalID generation that uses the adaptorValueClass() method of
EOAttribute which in turn uses the adaptorValueType() with only support 4 types
(String, Number, Data and NSTimestamp).
This part is totally broken with custom data type.
My conclusion is custom data type are not supported as PK attributes.
I create a work around in my DateMTA entity (used for report grouping by month,
quarter, year, ...)
static public DateMTA forDate(EOEditingContext ec, LocalDate date) {
synchronized (GLOBAL_ID) {
if (_gids == null) {
NSMutableDictionary<LocalDate, EOGlobalID> gids
= new NSMutableDictionary<LocalDate, EOGlobalID>();
for (DateMTA dateMTA : fetchAllDateMTAs(ec)) {
gids.setObjectForKey(dateMTA.globalId(), dateMTA.date());
}
_gids = gids.immutableClone();
}
EOGlobalID globalID = _gids.objectForKey(date);
return (DateMTA) ec.faultForGlobalID(globalID, ec);
}
}
and when I need the relationship, I add this to the entity class:
public static ERXKey<DateMTA> DATE_MTA = new ERXKey<DateMTA>("dateMta");
private DateMTA dateMta;
public DateMTA dateMta() {
if (dateMta == null) {
dateMta = DateMTA.forDate(editingContext(), date());
}
return dateMta;
}
It would be much nicer to simply create the relationship but for in memory
stuff, this works great and stiff very efficient.
Regards,
Samuel
