Carl J. Mosca commented on OLINGO-11:
-------------------------------------
This may be an oversimplification of the issue but I have made the following
change to
org.apache.olingo.odata2.processor.core.jpa.access.data.JPAExpandCallBack.
I assume there are other implications but finding none presently I think it
will help me learn the codebase.
