[CLOSED] ModelField useNull when populating from HTTP handler
The sample below shows that when I retrieve the TitleId, for ProductID = 3, from a store populated locally with the useNull="true" on the ModelField the value of the attribute in the data and raw objects of the store is NULL. When I retrieve it via an HTTP handler the data object of the store has 0, but the raw object has NULL.
Local Store (Data) - null
Local Store (Raw) - null
HTTP Store (Data) - 0
HTTP Store (Raw) - null
Am I doing something incorrectly in the JSON?
