[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3294) Exception Handling not working under certain conditions

Exception Handling not working under certain conditions ------------------------------------------------------- Key: JBSEAM-3294 URL: https://jira.jboss.org/jira/browse/JBSEAM-3294 Project: Seam Issue Type: Bug Affects Versions: 2.0.3.CR1 Environment: Kubuntu, Tomcat 6.0.14, Eclipse Europa 3.3.2 Reporter: Maximiliano Carrizo Priority: Minor Original Estimate: 1 day Remaining Estimate: 1 day I have the following action method: public String confirm() { log.info("---------> Saving Selected Role"); securityServices.confirmRole(roleOperationType, selectedRole); events.raiseTransactionSuccessEvent(Constant.REFRESH_ROLE_LIST); return Constant.SUCCESS; } This pages config ( exception trapping only ): <!-- Exceptions Trapping --> <exception class="javax.persistence.OptimisticLockException"> <end-conversation /> <redirect view-id="/pages/publicArea/errors/genericError.xhtml"> <message>#{messages['dirty_data_error']}</message> </redirect> </exception> <exception class="org.jboss.seam.security.AuthorizationException"> <end-conversation /> <redirect view-id="/pages/publicArea/errors/genericError.xhtml"> <message>#{messages['no_permission_granted']}</message> </redirect> </exception> <exception class="org.hibernate.StaleObjectStateException"> <end-conversation /> <redirect view-id="/pages/publicArea/errors/genericError.xhtml"> <message>#{messages['record_locked']}</message> </redirect> </exception> <exception class="java.lang.Throwable"> <end-conversation /> <redirect view-id="/pages/publicArea/errors/genericError.xhtml"> <message>#{messages['unknown_error']} #{org.jboss.seam.handledException.getMessage()}</message> </redirect> </exception> Im testing exception handling functionality of my app. When the service of my action: securityServices.confirmRole(roleOperationType, selectedRole); throws this exception: javax.faces.el.EvaluationException: javax.persistence.PersistenceException: org.hibernate.PropertyValueException: not-null property references a null or transient value: com.teracode.seamapp.security.model.Role.home at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:91) In some cases app works fine ( closes current long-running conversation, opens error page and shows error message ) and in other cases leaves conversation open and dont show error message. I do always the same testing steps over and over .... and sometimes fails and sometimes not. I couldnt find an error criteria, but, when I change parameter concurrent-request-timeout on components.xml, setting a big value, something funny happens. Imagine I set concurrent-request-timeout on ten seconds. If I execute action and app answers me instantly, app works fine. If action lasts for ten seconds, app fails. I thought on sending you an example, but I've tested app at my partners machines, and ...... had the same behavior. Best regards
