APAR status

  • Closed as program error.

Error description

  • The following WCM API methods that retrieve parent ids are slow
    when the code retrieves the parent from the strategy cache
     (after first failing to find a match in the absolute path
     cache) as the parent is unnecessarily cloned out of the cache:
       Content.getDirectParent
       Content.getParentId
       Category.getParentId
       Category.getParent
       SiteArea.getParentId
       SiteArea.getParent
       SiteArea.hasDirectContent
       SiteArea.hasSiteArea
       Site.hasSiteArea
