Subject [jira] [Updated] (OLINGO-1064) Complex type is deserialized as Primitive type if the value is NULL
Date Tue, 27 Dec 2016 06:37:58 GMT

     [ https://issues.apache.org/jira/browse/OLINGO-1064?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Punith DG updated OLINGO-1064:
------------------------------
    Description: 
The ODataClient deserializer wrongly converts the Complex Type field to Primitive Type field
if the value received for the complex type is NULL.

e.g. on querying Person data from OData TripPin service (https://services.odata.org/TripPinRESTierService)
I received below JSON response.

{
	"@odata.context": "http://services.odata.org/TripPinRESTierService/(S(myhztseklikbg41mbg03ugk5))/$metadata#People(AddressInfo,FavoriteFeature,FirstName,HomeAddress,LastName,UserName)",
	"value": [{
		"FavoriteFeature": "Feature1",
		"FirstName": "Angel",
		"Gender": "Female",
		"LastName": "Huffman",
		"UserName": "angelhuffman",
		"AddressInfo": [{
			"Address": "55 Grizzly Peak Rd.",
			"City": {
				"Name": "Butte",
				"CountryRegion": "United States",
				"Region": "MT"
			}
		}],
		"HomeAddress": null
	}]
}

See that 'HomeAddress' is ComplexType of type 'Location' and received 'null' value.

When you deserialize and get an entity, the HomeAddress property of the Person entity is set
to Primitive Type with null value. This could be complex type?

			"City": {
				"Name": "Butte",
				"CountryRegion": "United States",
				"Region": "MT"
			}
		}],
		"HomeAddress": null
	}]
}

See that HomeAddress is of complex type and received value is 'null'.

When you deserialize and get an entity, the HomeAddress (ComplexType of type 'Location') property
of the Person entity is set to Primitive Type with null value.
