    [ https://issues.apache.org/jira/browse/CAY-1250?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12765499#action_12765499 ] 

Donald Vrakking commented on CAY-1250:
--------------------------------------

Thanx, it works perfectly now.

Do you happen to have any plans to port the fixes to a 2.0.5, or does that require to much effort?

> Two entities;  A->B in a n:1 relation, B has a subentity. When prefetching B, the toOneFault on A isn't updated with the prefetched B. When B is accessed from A, an additional query is still executed to get B.
> It makes no difference if A has subentities or not.
> This occurs in 2.0.4 with a disjoint and joint prefetch. With 3.0M6 it only occurs when using a disjoint prefetch.
