-----------------------------------------
Hi Archana,
I'm creating a new entity and I'm sending something like this:
{"@odata.type":"#namespace.MyEntity","par...@odata.type":"#Collection(namespace.Param)","params":[{"@odata.type":"#namespace.StringParam","value":"1","i...@odata.type":"String","id":"stringParam1"}]}
The metadata is:
<EntityType Name="MyEntity">
<Property Name="params" Type="Collection(namespace.Param)"/>
</EntityType>
<ComplexType Name="Param" Abstract="true">
<Property Name="id" Type="Edm.String"/>
</ComplexType>
<ComplexType Name="StringParam" BaseType="namespace.Param">
<Property Name="value" Type="Edm.String"/>
</ComplexType>
Then I get this exception as the value property of the StringParam isn't read
as it is deserialized as a Param:
org.apache.olingo.server.api.deserializer.DeserializerException: Tree should be
empty but still has content left: value

> Error deserialization of complex collection with derived type
> -------------------------------------------------------------
>
> Key: OLINGO-1123
> URL: https://issues.apache.org/jira/browse/OLINGO-1123
> Project: Olingo
> Issue Type: Bug
> Affects Versions: (Java) V4 4.3.0
> Reporter: Frederik Zimmer
>
> If a complex collection which contains entries with derived types is
> deserialized the entries are deserialized with the collection type. This
> results then in an error "DeserializerException: Tree should be empty but
> still has content left" because the derived type has more properties which
> are not read.
> In ODataJsonDeserializer the method consumePropertyCollectionNode should
> check with the collection node specifies it's own type and then use this type
> for deserialization.
