[Dspace-tech] NullPointerException in CollectionRecentSubmissions
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 at map:transform type=CollectionViewer - resource://aspects/ViewArtifacts/sitemap.xmap:133:97 at map:transform type=Navigation - resource://aspects/ViewArtifacts/sitemap.xmap:72:59 ...

I've had a look at the code and apparently getRecentlySubmittedItems() returns null. Is this a known issue?

[Dspace-tech] After upgrade to DSpace 3.0 cannot add new items
Hello, I upgraded DSpace from version 1.8.2 to DSpace 3.0. but now I cannot add any new items to collections. I thought that installing DSpace Replication Suite 3.0 would solve the problem, but I still receive an error message when I click on Submit a new item to this collection.

Re: [Dspace-tech] After upgrade to DSpace 3.0 cannot add new items
Hi Alain, when installing the curation task and you copied the jar to [dspace]/lib, did you also copy the .jar to [dspace]/webapps/xmlui/WEB-INF/lib/ ? If not, XMLUI won't be able to load the class. Anyway, your emails sounds like you installed Replication Suite only because of this error. If you don't actually want Replication Suite, it might help to just remove the related task classes from the list of curation tasks in [dspace]/config/modules/curate.cfg.

You could probably copy the maps and change the transformer class to discovery, but I don't think it would work, because they have different URL parameters.

Jonathan - I'm not sure if you're using xmlui or jspui. I know that in xmlui, the servlet didn't implement content range.
