I'm having a problem after upgrading from 1.5.3 to 1.6.1 (or 1.6.0): when I try to browse by Author or Subject I get the following error:
java.lang.NullPointerException: Cocoon stacktrace [hide] Could not read resource cocoon://DRI/5/browse context:/resource://aspects/Administrative/sitemap.xmap - 957:31 <map:serialize type="xml"> context:/resource://aspects/Administrative/sitemap.xmap - 295:38 <map:transform type="Navigation"> context:/resource://aspects/Administrative/sitemap.xmap - 294:44 <map:transform type="SystemwideAlerts"> context:/resource://aspects/Administrative/sitemap.xmap - 292:19 <map:generate> context:/resource://aspects/EPerson/sitemap.xmap - 332:31 <map:serialize type="xml"> context:/resource://aspects/EPerson/sitemap.xmap - 137:38 <map:transform type="Navigation"> context:/resource://aspects/EPerson/sitemap.xmap - 126:19 <map:generate> context:/resource://aspects/Submission/sitemap.xmap - 342:27 <map:serialize> context:/resource://aspects/Submission/sitemap.xmap - 318:26 <map:generate> context:/resource://aspects/Statistics/sitemap.xmap - 70:31 <map:serialize type="xml"> context:/resource://aspects/Statistics/sitemap.xmap - 33:19 <map:generate> context:/jndi:/localhost/xmlui/aspects/aspects.xmap - 115:34 <map:serialize type="xml"> context:/jndi:/localhost/xmlui/aspects/aspects.xmap - 114:43 <map:transform type="PageNotFound"> context:/jndi:/localhost/xmlui/aspects/aspects.xmap - 113:22 <map:generate> context:/jndi:/localhost/xmlui/themes/Reference/sitemap.xmap - 184:62 <map:serialize type="xhtml"> context:/jndi:/localhost/xmlui/themes/Reference/sitemap.xmap - 181:112 <map:transform type="NamespaceFilter"> context:/jndi:/localhost/xmlui/themes/Reference/sitemap.xmap - 180:106 <map:transform type="NamespaceFilter"> context:/jndi:/localhost/xmlui/themes/Reference/sitemap.xmap - 174:68 <map:transform type="i18n"> context:/jndi:/localhost/xmlui/themes/Reference/sitemap.xmap - 170:72 <map:transform> context:/jndi:/localhost/xmlui/themes/Reference/sitemap.xmap - 155:87 <map:transform type="IncludePageMeta"> context:/jndi:/localhost/xmlui/themes/Reference/sitemap.xmap - 131:83 <map:generate type="file"> context:/jndi:/localhost/xmlui/themes/Reference/sitemap.xmap - 128:49 <map:match> context:/jndi:/localhost/xmlui/themes/themes.xmap - 63:45 <map:mount> context:/jndi:/localhost/xmlui/themes/themes.xmap - 62:35 <map:match type="ThemeMatcher"> context:/jndi:/localhost/xmlui/sitemap.xmap - 550:94 <map:mount> with this in the log: 2010-06-01 15:12:02,749 INFO org.dspace.browse.BrowseEngine @ anonymous:session_id=89F31FAB7C91C4CEA5F42FF5321A0565:ip_addr=10.4.36.39: browse_by_value:focus=null I saw stuff like this before related to the Emetsger Embargo patch. To get Author and Subject browse listings working after applying that patch, I had to edit dspace-api/src/main/java/org/dspace/browse/BrowseEngine.java. But it despite the similar symptom, this problem seems to be caused by something else as a Test instance upgraded (to 1.6.0) fine and works. (Unfortunately it is little old, so I'm faced with the prospect of having to redo any submissions that occurred since I made that copy if I choose to use it.) I'd appreciate any insights into what may have caused this, and how I can fix it.
