Hi all,
I'm having problems with inheritance, separate models, D2W and Oracle.
I'm getting the following exception:
java.lang.IllegalStateException: The object with globalID
_EOIntegralKeyGlobalID[Action (java.lang.Integer)1] could not be found
in the database. This could be result of a referential integrity problem
with the database. An empty fault could not be created because the
object's class could not be determined (e.g. the GID is temporary or it
is for an abstract entity).
I'll try to illustrate the situation: I have a model A with an entity X
and a model B with an entity Y. Y is abstract and is the super type for
Y' and Y'' entities. The entity X has a relationship with the abstract
entity Y. The inheritance uses the single table approach. So, Y' and Y''
records are saved in the same table Y.
There is a strange detail. This problem is not always reproducible and
sometimes everything just works as expected. I've verified and the
referenced record exists on database.
I found this thread [1] about the same subject, but there is no much
conclusion about the proper solution. I suspect the problem will
completely disappear if I merge both models. But I want to hear your
opinion first.
I'm using WO 5.4.1 and Wonder 4.0 (from 04-24-2008) by the way.
Thanks for any advice.
