Subject [jira] Commented: (OPENJPA-370) LoadFetchGroup annotation was not recognized during the fetch1
Date Thu, 01 Nov 2007 16:20:50 GMT

Kevin Sutter commented on OPENJPA-370:
--------------------------------------

Okay, my performance runs are not quite as drastic as the ones cited by Patrick, but they
still are not great.  And, given the concerns about our interpretation of the LoadFetchGroups
processing (via the testcase analysis), I will back out these changes from both the 1.0.x
and 1.1.0 branches.  I will do this this afternoon.

Thanks for the insights and the patience while we figure this out.  Teresa should be back
in the saddle next week and we can figure out the proper solution and proper interpretation
of LoadFetchGroups at that time (unless the collective "we" can do it before she gets back).

Thanks,
Kevin

> Employee class has a LoadFetchGroup annotation defined on the Rating field, when getRating
was called, the address should be returned also. However, openjpa did not handle the LoadFetchGroup
correctly, therefore, address was not eargly fetched.
> public class FGEmployee{
>     @Id
>     private int id;
>  
>     @OneToOne(fetch=FetchType.LAZY) 
>     private FGAddress address;
>  
>     @Basic(fetch=FetchType.LAZY)
>     @LoadFetchGroup("AddressFetchGroup")
>     private String rating;
>  
>     @ManyToOne(fetch=FetchType.LAZY)
>     private FGManager manager;
