Error: Some of the mappings are incomplete

Question

I am trying to generate a java diagram from tables that are located in two different schemas.
Table A, B are in the same schema.
A.id -> primary key
B.id -> primary key
There is a one to many mapping from B to A
I want to add a third table, C from another database to this.
Table C ( id, b_id ) -- where id is the primary key and b_id is the table B's primary key. Since these two tables are in different schema's there is no foreign key constraint.
There is a one - many relationship between B and C ( B can have multiple rows in C )
The way I have done this - using the Component Palette, done a one - many directed relationship.
When I try to generate the descriptors I get the following errors:
1. Mappung uses Indirection but its associated arrtibute is not a ValueHolderInterface
2. No table refernce is selected
3. Table reference is invalid because of the target table chosen.
Thanks

Answer 1

Did you modify the source code of B or C classes after creating a relationship through the diagram?
Furthermore, did you map the relationship using the mapping editor?
Just to let you know that unless a FK constraint exists, it is not possible to create relationships at the class level in the TopLink Mapping Editor in JDev.
Hope this helps.
