> Key: DS-1052
> URL: https://jira.duraspace.org/browse/DS-1052
> Project: DSpace
> Issue Type: Bug
> Components: DSpace API
> Reporter: Scott Phillips
> Assignee: Scott Phillips
> Priority: Major
> Attachments: DS-1052.patch

>
> Almost all items in DSpace have a dc.date.accessioned because it is
> automatically assigned when the item is created. There are two conditions
> which can occur that causes an item to get lose it's accessioned date.
> 1) A person with editing privileges on an item removes the
> dc.date.accessioned metadata field.
> 2) The item's accessioned date is created via the InstallItem.restore()
> method.
> When one of these conditions occur the item gets inserted into the browsing
> sort table with a null value. When ever a recent submission query is run
> these items will always be returned first because Postgres and Oracle always
> return NULLS first when executing an ORDER BY clause. This means that these
> items are permanently penned at the top of the RSS feed and recent
> submissions sections sections.
