-------------------------------------
Summary: Serializer for complex collection properties does not
respect $select
Key: OLINGO-1231
URL: https://issues.apache.org/jira/browse/OLINGO-1231
Project: Olingo
Issue Type: Bug
Components: odata4-server
Affects Versions: (Java) V4 4.4.0
Reporter: Oliver Grande
I have an entity type that contains a complex collection property:
{code:xml}
<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)">
{code}
Now I can try to restrict the returned columns using $select:
{code:java}
.../Persons('99')/InhouseAddress?$select=Building,TaskID{code}
The serializer (JSON as well as XML) do not respect the $select and fills all
not retrieved properties with null:
{code:xml}
<m:value m:type="#Collection(dummy.InhouseAddress)"
m:context="$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>
{code}
It looks like this is because _ODataXmlSerializer.complexCollection_ sets the
parameter selectedPaths to _null_ when calling writeComplexValue
