NPE in ConversationEntry ------------------------ Key: JBSEAM-1078 URL: http://jira.jboss.com/jira/browse/JBSEAM-1078 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 1.2.0.GA Reporter: Petr Ferschmann Priority: Minor Sometime when some kind of error happens I receive NPE java.lang.NullPointerException at org.jboss.seam.core.ConversationEntry.<init>(ConversationEntry.java:44) at org.jboss.seam.core.ConversationEntries.createConversationEntry(ConversationEntries.java:50) at org.jboss.seam.core.Manager.createConversationEntry(Manager.java:649) at org.jboss.seam.core.Manager.beforeRedirect(Manager.java:796) at org.jboss.seam.exceptions.DebugPageHandler.handle(DebugPageHandler.java:25) at org.jboss.seam.core.Exceptions.handle(Exceptions.java:70) at org.jboss.seam.web.ExceptionFilter.endWebRequestAfterException(ExceptionFilter.java:91) at org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:73) at org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:49) at org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:53) at org.jboss.seam.web.MultipartFilter.doFilter(MultipartFilter.java:74) at org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:49) at org.jboss.seam.web.SeamFilter.doFilter(SeamFilter.java:84) And there is: this.conversationIdStack = stack==null ? null : Collections.unmodifiableList(stack); if ( conversationIdStack.size()>1 ) So I think it is expected that stack is null (there is a check).
