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":

EDITED

My own answer: It is possible by passing an object as value of the attribute.

ngsi.updateAttributes([
{
'entity':

,
'attributes':[{
"name":"location","contextValue": {
"attrName": "position",
"coords":

}
}]
}
],

);

However, Wirecloud is using NGSI API v1, therefore all attributes are treated as strings when they are sent/received to/from Orion.
