             Summary: Problem when updating a navigation link with cardinality n > 1
                 Key: OLINGO-512
                 URL: https://issues.apache.org/jira/browse/OLINGO-512
             Project: Olingo
          Issue Type: Bug
          Components: odata4-client
    Affects Versions: V4 4.0.0-beta-01
         Environment: java version : "1.7.0_72" 
Odata v4 service : http://services.odata.org/V4/OData/(S(li4s4wcplcgyiy3uvuog1lxl))/OData.svc
            Reporter: Thierry Templier


I try to update a navigation link of an entity with cardinality n>1 as described below:

String serviceRoot = (...);
URI productUri = client.newURIBuilder(serviceRoot)
    .appendEntitySetSegment("Products")
    .appendKeySegment(1)
    .build();

ODataEntity productUpdates = client.getObjectFactory().newEntity(
    new FullQualifiedName("ODataDemo", "Product"));

URI categoryRef = client.newURIBuilder(serviceRoot)
    .appendEntitySetSegment("Categories")
    .appendKeySegment(2)
    .build();

ODataLink category = client.getObjectFactory()
    .newEntityNavigationLink("Categories", categoryRef);
productUpdates.getNavigationLinks().add(category);

ODataEntityUpdateRequest<ODataEntity> req = client
    .getCUDRequestFactory().getEntityUpdateRequest(productUri,
                      UpdateType.PATCH, productUpdates);

ODataEntityUpdateResponse<ODataEntity> res = req.execute();

I have the following error. The target service expects an array and a string is sent. See request and response below.

Here is the simplified content of the request:

PATCH /V4/OData/(S(li4s4wcplcgyiy3uvuog1lxl))/OData.svc/Products(1)
{
  "@odata.type":"#ODataDemo.Product",
  "Categories@odata.bind":"http://localhost:8080/V4/OData/(S(li4s4wcplcgyiy3uvuog1lxl))/OData.svc/Categories(2)"
}

and the simplified content of the response:

HTTP/1.1 400 Bad Request
{"error":{"code":"","message":"An error occurred while processing this request.","innererror":{"message":"The resource set reference navigation property 'Categories' has a property annotation 'odata.bind' with a string value. Resource set reference navigation properties can only have a property annotation 'odata.bind' with an array value.","type":"Microsoft.OData.Core.ODataException","stacktrace":"   at "}}}
