[jira] [Resolved] (OLINGO-1129) ODataJsonSerializer Does Not
Support Derived Type in $expand Option
[ https://issues.apache.org/jira/browse/OLINGO-1129?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ramya resolved OLINGO-1129.
---------------------------
Resolution: Fixed
> ODataJsonSerializer Does Not Support Derived Type in $expand Option
> -------------------------------------------------------------------
>
> Key: OLINGO-1129
> URL: https://issues.apache.org/jira/browse/OLINGO-1129
> Project: Olingo
> Issue Type: New Feature
> Components: odata4-server
> Affects Versions: (Java) V4 4.3.0
> Reporter: Hui Wang
> Priority: Minor
>
> Currently we need to use type casting to a derived type in $expand. Here is the corresponding part in the OData Protocol.
> http://docs.oasis-open.org/odata/odata/v4.0/errata03/os/complete/part2-url-conventions/odata-v4.0-errata03-os-part2-url-conventions-complete.html#_Toc453752352
> To reproduce:
> Here is an example URL provided in the documentation that could be used for reproducing the defect:
> http://host/service/Orders?$expand=Customer/Model.VipCustomer
> In the current 4.3 version, ODataJsonSerializer only deals with expand on Customer but ignores the type filter Model.VipCustomer. It means, the response would only show the content of super type Customer. Any custom properties in derived type VipCustomer wouldn't be returned.
