Hi Mark, Actually, it looks like helix84 was accidentally looking at the wrong "CommunityRecentSubmissions" class. Your underlying error is coming from Discovery, i.e. this class
https://github.com/DSpace/DSpace/blob/dspace-1.7.2/dspace-discovery/dspace-discovery-xmlui-api/src/main/java/org/dspace/app/xmlui/aspect/discovery/CommunityRecentSubmissions.java#L75 That error seems to be saying that Apache Solr (which is used by Discovery) is returning a "null" result set (at least for the set of recent submissions for that Community). This implies to me that something may be going on in Solr. Either your DSpace is having trouble finding Solr, or else your Solr index has gotten corrupted. You could try reindexing all content in Discovery, to see if that helps: ./bin/dspace update-discovery-index (You could also add the "-b" flag to completely wipe the existing index and rebuild from scratch.) If this reindex command also throws an error, it's possible your Solr configs, in ./config/dspace-solr-search.cfg, are messed up somehow. Some additional info on Discovery configs is at: https://wiki.duraspace.org/display/DSDOC17/Discovery - Tim On 8/14/2013 4:59 PM, helix84 wrote: >> Caused by: java.lang.NullPointerException >> at >> org.dspace.app.xmlui.cocoon.AbstractDSpaceTransformer.handleException(AbstractDSpaceTransformer.java:109) > > https://github.com/DSpace/DSpace/blob/dspace-1.7.2/dspace-xmlui/dspace-xmlui-api/src/main/java/org/dspace/app/xmlui/cocoon/AbstractDSpaceTransformer.java#L109 > > I'm not sure whether this tells us that SAXException couldn't be > instantiated or that something else is null; which would be "this", i.e. > the AbstractDSpaceTransformer class. > >> Caused by: java.lang.NullPointerException >> at >> org.dspace.app.xmlui.aspect.discovery.CommunityRecentSubmissions.addBody(CommunityRecentSubmissions.java:75) > > > https://github.com/DSpace/DSpace/blob/dspace-1.7.2/dspace-xmlui/dspace-xmlui-api/src/main/java/org/dspace/app/xmlui/aspect/artifactbrowser/CommunityRecentSubmissions.java#L75 > > This one's strange - line 75 is in the getKey() method, but your error > repors it's in the addBody() method.
