[jira] Created: (JDO-330) JPOX fails to populate fields in fetch
plan during detachCopy
JPOX fails to populate fields in fetch plan during detachCopy
-------------------------------------------------------------
Key: JDO-330
URL: http://issues.apache.org/jira/browse/JDO-330
Project: JDO
Type: Bug
Components: tck20
Versions: JDO 2 rc1

After applying the patch in JDO-272, JPOX fails:
[java] 1) testDetachCopy(org.apache.jdo.tck.api.persistencemanager.detach.DetachCopy)javax.jdo.JDODetachedFieldAccessException: You have just attempted to access field "cart" yet this field was not detached when you detached the object. Either dont access this field, or detach the field when detaching the object.

The field is part of the fetch plan in effect when the instances are detached.

[jira] Resolved: (JDO-330) JPOX fails to populate fields in fetch
plan during detachCopy
Posted by "Craig Russell (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/JDO-330?page=all ]
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.
