Description

I have an entity type that contains a complex collection property:

 

<EntityType Name="Person">
  <Property Name="BirthDay" Type="Edm.Date"/>
  <Property Name="LastName" Type="Edm.String" MaxLength="255"/>
  <Property Name="FirstName" Type="Edm.String" MaxLength="255"/>
  <Property Name="InhouseAddress" Type="Collection(dummy.InhouseAddress)">

 

Now I can try to restrict the returned columns using $select:

 

.../Persons('99')/InhouseAddress?$select=Building,TaskID

The serializer (JSON as well as XML) do not respect the $select and fills all not retrieved properties with null: 

<m:value m:type="#Collection(dummy.InhouseAddress)" m:context="$metadata#Persons/InhouseAddress">
<m:element>
   <d:RoomNumber m:null="true"/>
   <d:Floor m:null="true"/>
   <d:TaskID>DEV</d:TaskID>
   <d:Building>1</d:Building>
</m:element>
</m:value>

 
It looks like this is because ODataXmlSerializer.complexCollection sets the parameter selectedPaths to null when calling writeComplexValue
