Jira issue originally created by user adyballa:
SetFetchmode is now woriking in AbstractQuery.
Why dont implement setFetchMode and perhaps further temporarily changes in an ClassMetadata-managing Object. Perhaps to work with a temporarily copy to allow a reset after some action.
Comment created by @ocramius:
Contextual changes in the entire UoW can lead to hard to predict situation that we don't want nor need to implement, as they represent additional complexity.
