I have some entities like:
Entity A (is abstract)
Relationship A. Is many to many with Entity X and it has an
intermediate Entity AX)
Entity B (is sub entity of Entity A)
Relationship A (inherit)
Relationship B
Entity C (is sub entity of Entity A)
Relationship A (inherit)
Relationship C
Entity D (is sub entity of Entity A)
Relationship A (inherit)
Relationship D
The Entity AX has something like this:
X_id A_id
1 1 Belongs to Entity B
2 3 Belongs to Entity C
4 5 Belongs to Entity B
5 6 Belongs to Entity D
5 7 Belongs to Entity C
3 8 Belongs to Entity B
When I start my application, I fetch EO's from entities B, C and D,
pre-fetching its relationships.
I fetch Entity B and pre-fetch relationship A and relationship B. When the
relationship A is pre-fetched, all the rows from Entity AX were fetched and
the Database Context create Global ID's for all of them (1,3,5,6,7,8) for
Entity B, but some of them belong to entity C and D.
When I fetch Entity C and D, some EO's has a Global ID of Entity B. The
issue generate a NPE at Database Context when a fault at relationship C is
solved. It's because the Global ID for EO C is from Entity B not Entity C.
Does my model have something wrong?
How to solve it? Any ideas.
Regards
Federico
