[Pharo-users] NeoJSON mapping of nil properties

Hi all... and Sven ;-) I'm mapping my objects with NeoJSONWriter, and I found it is not writing the properties whose values are null. NeoJSONPropertyMapping>>#writeObject: anObject on: jsonMapWriter | value | value := getter value: anObject. value ifNotNil: [ jsonMapWriter writeKey: propertyName value: value as: valueSchema ] It is a good default (saves space, and cpu cycles). But in my case the consumer of the JSON objects expect the objects to have all the attributes previously defined. Is there a way I can configure the mapper or the mapping to write null when the value is nil? Thank you! Esteban A. Maringolo
