> +Question:+
> NGSI update attributes from complex entities in Wirecloud
> +Description:+
> Is it possible to update a child attribute through the updateAttributes() function from Wirecloud NGSI API?
> For example, a coordinate (entity.location.coords.coordinates[0]=-2.000000) in this piece of entity.
>    "attrNames": [ "A1", "A2", "position" ],
>    "creDate": 1389376081,
>    "modDate": 1389376244,
>    "location": {
>        "attrName": "position",
>        "coords": {
>            "type": "Point",
>            "coordinates": [ -3.691944, 40.418889 ]
>        }
> EDITED
> My own answer: It is possible by passing an object as value of the attribute.

>                           "name":"location","contextValue": {

>                                      "type": "Point",
>                                      "coordinates": [ -2.000000, 40.418889 ]
>                                }
>                           } 
>                         }]  
>                     }
>                 ], {
>                     onSuccess: onUpdateAttributesSuccess,
>                     onFailure: onUpdateAttributesFail
>                 }
>             );
> However, Wirecloud is using NGSI API v1, therefore all attributes are treated as strings when they are sent/received to/from Orion.
