--------------------------------------

             Summary: OData V4 requests for property and navigationproperty values of complexTypes that are not included in the selected items are ignored
                 Key: OLINGO-1307
                 URL: https://issues.apache.org/jira/browse/OLINGO-1307
             Project: Olingo
          Issue Type: Bug
          Components: odata4-server
    Affects Versions: (Java) V4 4.4.0
            Reporter: Peter Lawrence


*URL Request*

Unsuccessful:
{code:java}
Employee('NWD~ContractEmployee-1')?$expand=employer/contractEmployer($select=label,subjectId){code}
Successful:
{code:java}
Employee('NWD~ContractEmployee-1')?$select=employer&$expand=employer/contractEmployer($select=label,subjectId){code}
*Steps to reproduce the problem:*
 The OData model contains a complexType, with navigationProperties as values:
{code:java}
 <EntityType Name="Employee" OpenType="true">
  <Key>
    <PropertyRef Name="subjectId"/>
  </Key>
  <Property Name="subjectId" Type="Edm.String" Nullable="false"/>
  ...
  <Property Name="employer" Type="northwind.employer"/>
  ...
 </EntityType>
<ComplexType Name="employer">
 <NavigationProperty Name="contractEmployer" Type="Collection(northwind.Shipper)"/>
 <NavigationProperty Name="parttimeEmployer" Type="Collection(northwind.Supplier)"/>
 </ComplexType>
{code}
 

*Other information*

This was raised originally with the OpenUI5 project as it was thought that the $select should have been included in the request. However they have responded saying it is indeed not necessary according to the standard:([https://github.com/SAP/openui5/issues/2235#issuecomment-428106366])
