Tilo Eilebrecht commented on OLINGO-1156:
-----------------------------------------
Increasing Priority to Blocker as this stops our development. In my eyes this
is a major point - it makes it impossible to work with objects that have
navigation properties (at least when theys need to be updated).
> ODataJPAServiceFactory - Cannot create or update entry with ManyToOne

> Key: OLINGO-1156
> URL: https://issues.apache.org/jira/browse/OLINGO-1156
> Project: Olingo
> Issue Type: Bug
> Components: odata2-jpa
> Affects Versions: V2 2.0.9
> Environment: EclipseLink 2.5.2
> Reporter: Tilo Eilebrecht
> Priority: Blocker
> Attachments: Alternative.java, Scope.java
>
>
> My project uses ODataJPAServiceFactory as described in the tutorial for JPA.
> I have an entity which references another entity with a ManyToOne
> relationship. If I submit a create or change request, the reference
> (idAlternative) is not created or updated. As the field is not nullable,
> object creation fails altogether.
> See my Entities in the attachment. The JoinColumn is idAlternative.
> I have investigated into possible causes and I stumbled on
> org.apache.olingo.odata2.jpa.processor.core.access.dataJPAEntity, method
> write. This method identifies idAlternative as an embeddable key and removes
> it from the propertyNames set. Therefore it does not get written into the
> object.
