[jira] [Commented] (OLINGO-711) Using an Entity in an Embeddable Object

["Chandan V.A (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OLINGO-711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14607914#comment-14607914 ] 

Chandan V.A commented on OLINGO-711:
------------------------------------

Hello Gregory,
Having JPA relationships inside embeddable types are not supported. Because Embeddable types in JPA entity definitions are transformed into Complex Types in OData model. In your case JPA processor cannot map such definitions to OData metadata definition.

You could get more detailed errors by executing the HTTP request with odata-debug=json query parameter.

Thanks
Kind regards
Chandan
