             Summary: ODataJsonSerializer fails to write Collections of Complex Properties
                 Key: OLINGO-501
                 URL: https://issues.apache.org/jira/browse/OLINGO-501
             Project: Olingo
          Issue Type: Bug
          Components: odata4-server
    Affects Versions: V4 4.0.0-beta-01, (Java) V4 4.0.0-beta-02
            Reporter: Michael Burwig
            Priority: Critical


Affected Method:
org.apache.olingo.server.core.serializer.json.ODataJsonSerializer.writeComplexCollection(type, property, ...)

The method writeComplexCollection iterates over the properties of a collection of properties and calls writeComplexValue(...).

{code:title=ODataJsonSerializer.java|borderStyle=solid}
...
for (Object value : property.asCollection()) {
  switch (property.getValueType()) {
  case COLLECTION_LINKED_COMPLEX:
    writeComplexValue(type, ((LinkedComplexValue) value).getValue(), selectedPaths, json);
    break;
  case COLLECTION_COMPLEX:
    writeComplexValue(type, property.asComplex(), selectedPaths, json);
    break;
...
{code}

The COLLECTION_COMPLEX case seems broken and should rather be something like:

{code:title=ODataJsonSerializer.java|borderStyle=solid}
...
  case COLLECTION_COMPLEX:
    writeComplexValue(type, ((Property) value).asComplex(), selectedPaths, json);
    break;
...
{code}
