[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-3368) conversation id evaluated to null (natural conversations)

conversation id evaluated to null (natural conversations) --------------------------------------------------------- Key: JBSEAM-3368 URL: https://jira.jboss.org/jira/browse/JBSEAM-3368 Project: Seam Issue Type: Bug Components: Core Affects Versions: 2.0.3.CR1 Environment: Linux Ubuntu 7.10, Intel Pentium 4, 3GHz, 1 GB RAM, Tomcat 6.0.16 Reporter: Arron Ferguson Assignee: Shane Bryzak Priority: Critical Fix For: 2.1.0.GA Attachments: conversation-src.tar.gz, jarfileslist.txt If the user attempts to go to a page that is restricted based on what is in the pages.xml file, two things go wrong: 1) an exception is thrown (java.lang.IllegalStateException: conversation id evaluated to null: [name of natural conversation]), 2) the user can still view the page that is supposed to be restricted (i.e., using the restrict element in the pages.xml file). Setup Instructions: 1.) Set up Tomcat 6.x 2.) Create web app project structure 3.) Use the following for your pages.xml file (copy/paste): <?xml version="1.0" encoding="UTF-8"?> <pages xmlns="http://jboss.com/products/seam/pages" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.0.xsd" http-port="8080" https-port="8443" no-conversation-view-id="/index.xhtml" login-view-id="/index.xhtml"> <conversation name="regmem" parameter-name="memberID" parameter-value="#{memberreg.tempKey}"/> <page view-id="*" scheme="http" /> <page view-id="/register.xhtml"> <description>Register Member: #{memberreg}</description> <navigation from-action="#{memberreg.start}"> <begin-conversation join="true" conversation="regmem"/> <redirect view-id="/register1.xhtml"/> </navigation> <navigation> <rule if="#{identity.loggedIn}"> <redirect view-id="/memberadmin.xhtml"/> </rule> <rule if="#{memberreg.acceptedInformation}"> <redirect view-id="/register3.xhtml"/> </rule> <rule if="#{memberreg.agree}"> <redirect view-id="/register2.xhtml"/> </rule> <rule if="#{memberreg.started}"> <redirect view-id="/register1.xhtml"/> </rule> </navigation> </page> <page view-id="/register1.xhtml" conversation-required="true" conversation="regmem"> <description>Register Member: #{memberreg}</description> <restrict>#{memberreg.started}</restrict> <navigation from-action="#{memberreg.agreeToLicense}"> <redirect view-id="/register2.xhtml"/> </navigation> <navigation from-action="#{memberreg.cancel}"> <end-conversation/> <redirect view-id="/index.xhtml"/> </navigation> <navigation> <rule if="#{identity.loggedIn}"> <redirect view-id="/memberadmin.xhtml"/> </rule> <rule if="#{memberreg.acceptedInformation}"> <redirect view-id="/register3.xhtml"/> </rule> <rule if="#{memberreg.agree}"> <redirect view-id="/register2.xhtml"/> </rule> </navigation> </page> <page view-id="/register2.xhtml" conversation-required="true" conversation="regmem"> <description>Register Member: #{memberreg}</description> <restrict>#{memberreg.agree}</restrict> <navigation from-action="#{memberreg.next}"> <rule if="#{memberreg.readyToConfirm}"> <redirect view-id="/register3.xhtml"/> </rule> <rule if="#{not memberreg.readyToConfirm}"> <redirect view-id="/register2.xhtml"/> </rule> </navigation> <navigation> <rule if="#{identity.loggedIn}"> <redirect view-id="/memberadmin.xhtml"/> </rule> <rule if="#{memberreg.acceptedInformation}"> <redirect view-id="/register3.xhtml"/> </rule> </navigation> </page> <page view-id="/register3.xhtml" conversation-required="true" conversation="regmem"> <description>Register Member: #{memberreg}</description> <restrict>#{memberreg.readyToConfirm}</restrict> <navigation from-action="#{memberreg.acceptInformation}"> <redirect view-id="/register4.xhtml"/> </navigation> <navigation from-action="#{memberreg.editInformation}"> <redirect view-id="/register2.xhtml"/> </navigation> <navigation> <rule if="#{identity.loggedIn}"> <redirect view-id="/memberadmin.xhtml"/> </rule> </navigation> </page> <page view-id="/register4.xhtml" conversation-required="true" conversation="regmem"> <description>Register Member: #{memberreg}</description> <restrict>#{memberreg.acceptedInformation}</restrict> <navigation from-action="#{memberreg.end}"> <end-conversation before-redirect="false"/> <redirect view-id="/index.xhtml"/> </navigation> </page> <!-- START EXCEPTIONS --> <exception class="org.jboss.seam.security.NotLoggedInException" log="false"> <redirect view-id="/index.xhtml"> <message severity="warn">Your session ended or expired.</message> </redirect> </exception> <exception class="org.jboss.seam.security.AuthorizationException" log="false"> <end-conversation/> <redirect view-id="/index.xhtml"> <message severity="warn">You are not authorized.</message> </redirect> </exception> <!-- END EXCEPTIONS --> </pages> 4.)

Create XHTML files (template, index, register1 - register4): /////////////////////////////////// template.xhtml: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" > <head> <title>something.com</title> </head> <body> <div> <h:messages globalOnly="true"/><br/><br/> <ui:insert name="maincontent"> </ui:insert> </div> </body> </html> /////////////////////////////////// index.html: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:s="http://jboss.com/products/seam/taglib"> <!-- <ui:composition template="./template.xhtml"> --> <ui:composition template="./template.xhtml"> <ui:define name="maincontent"> <s:link view="/register.html" value="click here to register" propagation="none"/> </ui:define> </ui:composition> </html> /////////////////////////////////// register.html <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:s="http://jboss.com/products/seam/taglib"> <ui:composition template="./template.xhtml"> <ui:define name="maincontent"> <p>Click to start natural conversation:</p> <h:form id="testform"> <h:outputText value="Click: "/> <h:commandButton value="Register" action="#{memberreg.start}"> <s:conversationName value="regmem"/> <s:conversationPropagation type="join"/> </h:commandButton> </h:form> </ui:define> </ui:composition> </html> /////////////////////////////////// register1.xhtml <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:s="http://jboss.com/products/seam/taglib" > <ui:composition template="./template.xhtml"> <ui:define name="maincontent"> <h:form id="agreeform"> <h:commandButton id="agreebut1" value="Agree" action="#{memberreg.agreeToLicense}"> <s:conversationName value="regmem"/> <s:conversationPropagation type="join"/> </h:commandButton> <br/><p>Click cancel to kill the natural conversation early</p> <h:commandButton id="disagreebut1" value="Disagree" action="#{memberreg.cancel}"> <s:conversationName value="regmem"/> <s:conversationPropagation type="end"/> </h:commandButton> </h:form> </ui:define> </ui:composition> </html> /////////////////////////////////// register2.xhtml <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:s="http://jboss.com/products/seam/taglib" > <ui:composition template="./template.xhtml"> <ui:define name="maincontent"> <h:form id="formfields"> <p>Content inserted for testing purposes when this button clicked:</p> <h:commandButton id="next" value="Next" action="#{memberreg.next}"> <s:conversationName value="regmem"/> <s:conversationPropagation type="join"/> </h:commandButton> </h:form> </ui:define> </ui:composition> </html> /////////////////////////////////// register3.xhtml <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:rich="http://richfaces.org/rich" xmlns:s="http://jboss.com/products/seam/taglib" > <ui:composition template="./template.xhtml"> <ui:define name="maincontent"> <h:form id="formfields" rendered="#{not identity.loggedIn}"> <h:commandButton id="editinfo" value="Edit Information" action="#{memberreg.editInformation}"> <s:conversationName value="regmem"/> <s:conversationPropagation type="join"/> </h:commandButton> &#160;&#160;&#160;&#160;&#160; <h:commandButton id="confirmreg" value="Confirm Registration" action="#{memberreg.acceptInformation}"> <s:conversationName value="regmem"/> <s:conversationPropagation type="join"/> </h:commandButton> </h:form> </ui:define> </ui:composition> </html> /////////////////////////////////// register4.xhtml <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:s="http://jboss.com/products/seam/taglib" > <ui:composition template="./template.xhtml"> <ui:define name="maincontent"> <p>Click back to finish natural conversation.</p> <s:link value="Back to home." action="#{memberreg.end}" propagation="end"/> </ui:define> </ui:composition> </html> 6.) Use the following JARs for your web app (for running inside of Tomcat 6): activation.jar antlr.jar asm.jar cglib.jar commons-beanutils.jar commons-codec-1.3.jar commons-collections.jar commons-digester.jar commons-lang.jar commons-logging.jar DA.jar dom4j.jar ejb-api.jar filelist.txt hibernate-annotations.jar hibernate-commons-annotations.jar hibernate-entitymanager.jar hibernate.jar hibernate-search.jar hibernate-validator.jar javassist.jar jboss-archive-browsing.jar jboss-el.jar jboss-seam-debug.jar jboss-seam-ioc.jar jboss-seam.jar jboss-seam-mail.jar jboss-seam-ui.jar jsf-api.jar jsf-facelets.jar jsf-impl.jar jstl.jar jta.jar lucene-core.jar mail.jar persistence-api.jar richfaces-api.jar richfaces-impl.jar richfaces-ui.jar spring.jar urlrewrite-3.1.0.jar 7.) (Optional) Set up facelets but you may also want to make the default extension html: <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping> Steps to reproduce bug: 1.) Start web app inside of Tomcat 6 2.) using your browser's URL text field, type in the name of a register1.html, register2.html, or register3.html. At this point your web app will generate an exception stack which will be caused by: java.lang.IllegalStateException: conversation id evaluated to null: The conversation is evaluated to null. Since conversations are a layer on top of sessions, the same behavior is expected which is a faces message purporting of no conversation existing and a redirect to the URL specified in the pages.xml attribute no-conversation-view-id="/index.xhtml" (so in this case index.xhtml page). It should not allow the user to see the page and generate exceptions.
