Concurrent task claiming and editing of metadata possible for same item in
submission workflow
----------------------------------------------------------------------------------------------
Key: DS-918
URL: https://jira.duraspace.org/browse/DS-918
Project: DSpace
Issue Type: Bug
Components: DSpace API, XMLUI
Affects Versions: 1.7.1, 1.7.0, 1.6.2
Reporter: Bill Hays
Context: EPerson A and EPerson B are in the Edit Workflow group of a collection
and use XMLUI for workflow.
It is possible for EPerson B to edit a workflowitem that has been claimed by
EPerson A
if the task list screen in XMLUI was rendered to EPerson B before the task was
claimed.
Both EPersons can edit the same item metadata simultaneously and the resulting
metadata
after both save can, but not always, be a combination of those edits.
If EPerson B clicks on the link to an individual workflow item in the displayed
list, s/he
is advanced to the screen that should be only for a successful claimer and can
then
select "Edit metadata". So there seem to be several places where checks for
workflowitem
ownership could be made but aren't.
If on the other hand EPerson B checks an item on such a stale displayed list,
then
the returned list does not show the item in the owned list. However if EPerson
A then
returns the same item to the pool, then B is silently advanced as the owner.
It is not the case that the dspace-api allows a second eperson to claim the item
rather it looks like XMLUI ignores the owner and allows another to edit or even
see the owner screen
so the save metadata action is not checking the owner vs. the eperson or ??
I tested this on both 1.6.2 and 1.7.1 with the same results
