Hi all,
every once in a while I get a NullPointerException at
CollectionRecentSubmissions (line 147) when browsing
communities/collections (Manakin 3.0). The log says the following:
org.apache.cocoon.ProcessingException: Failed to process pipeline
at <map:serialize type="xml"> -
resource://aspects/ViewArtifacts/sitemap.xmap:134:84

...
Caused by: org.xml.sax.SAXException: An error was encountered while
processing the 'aspect.artifactbrowser.CollectionRecentSubmissions' Wing

Restarting Tomcat resolves the issue, but clearly that's not very
practical. I've had a look at the code and apparently
getRecentlySubmittedItems() returns null. Is this a known issue?
Thanks,
Joachim
