[MDSAL-647] org.opendaylight.mdsal.binding.model.ietf.rfc8776 generated classes from typedef -> typedef -> enumeration

Tue, 2 May 2023 19:43:39 +0000

In ietf-te-types yang model there is a type definition “te-common-status” which type is enumeration. This type definition is used to declare 2 another type definitions:

  typedef te-oper-status {
    type te-common-status;
    description
      "Defines a type representing the operational status of
       a TE resource.";
  }

  typedef te-admin-status {
    type te-common-status;
    description
      "Defines a type representing the administrative status of
       a TE resource.";
  }

The generated classes from te-oper-status (org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.te.types.rev200610. TeOperStatus) and te-admin-status (org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.te.types.rev200610. TeAdminStatus) are empty Class. Shouldn’t they be Enum instead ? I ask this question because when I try to serialize object using them I got the following exception

I have attached to this mail a code sample to reproduce the problem.
