VO with reference flag indirect relation = EntityImpl not retrieved?

Question

Hi,
JClient 10.1.2
I have a ViewObject VOabcd based on 4 entities:
EntityA,EntityB,EntityC and EntityD.
ViewObject VOabcd is part of package 2.
EntityA is updateable and is part of package 2.
EntityB,EntityC and EntityD have reference flag set.
EntityB, EntityC and EntityD are part of package 1.
EntityA has foreign key association with EntityB: (*,1) relation.
EntityB has foreign key association with EntityC: (*,1) relation.
EntityB has foreign key association with EntityD: (*,1) relation.
Only the fields of EntityA are updateable so no set methods for attributes of the entities in the VO.
When I set the foreign attribute to EntityB all fields of EntityB are displayed automatically but the attributes of EntityC and EntityD are not retrieved as expected?
I have no set methods so I can't retrieve those attributes manually.
Your help is requested.
Thanks
Frederic
For your info, a VO in package 1 based on the same relations of EntityB,EntityC,EntityD works as expected.
For your info, extract of VO.xml file:
<EntityUsage

</DesignTime>
</EntityUsage>

Answer 1

I found the solution/problem.
The foreign key attributes of EntityB to EntityC and EntityD were not in the VO.
When creating a new row in JClient, in order to display automatically the attributes of a referenced entity when entering the foreign key attribute the following is required:
- the reference flag must be set
- the foreign key must be in the VO
- the primary key of the referenced Entity must be in the VO (automatically added by the VO editor).
My question:
When you shuffle an attribute of a referenced Entity the PK attributes are automatically added.
Why aren't the foreign key attributes automatically added?
Thanks
