Craig Russell resolved JDO-330:
-------------------------------
Resolution: Invalid
Assign To: Craig Russell
This was a user error. The FetchPlan used the default MaxFetchDepth which is 1.
None of the related instances' fields were set by the detach because of this
error.
This highlights an interesting usability issue with FetchPlan. The default
FetchPlan MaxFetchDepth is designed to avoid accidentally retrieving the entire
database into memory, but it needs to be carefully thought about.
