I'm a bit lost here. I'm trying to encode a ERCalendar object in JSON, and I'm
getting problems. That object (coming from ERCalendar2) also have a array that
contains EREvent objects.
So I did that:
JSONSerializer serializer = new JSONSerializer();
serializer.registerDefaultSerializers();
serializer.registerSerializer(new ERXBeanSerializer(EREvent.class));
serializer.registerSerializer(new ERXBeanSerializer(ERCalendar.class));
serializer.registerSerializer(new NSArraySerializer());
But I'm getting Java heap space errors (see full stack below).
If I don't serialize EREvent, no errors, but the EREvent objects are not
serialized. So I guess something make the serializer to go an infinite loop in
EREvent, but I don't know what.
Any suggestions?
