[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3368) conversation id evaluated to null (natural conversations)
by Arron Ferguson (JIRA)
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
Priority: Blocker
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"?>

public void setFirstName(String firstName) { this.firstName = firstName; }
@Override

}
5.) Create XHTML files (template, index, register1 - register4):

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.

Need an option to remove URL parameters from a URL
--------------------------------------------------
Key: JBSEAM-2310
URL: http://jira.jboss.com/jira/browse/JBSEAM-2310
Project: JBoss Seam
Issue Type: Feature Request
Components: Core
Affects Versions: 1.2.1.GA
Environment: All environments
Reporter: Terry
Priority: Minor
When JSF page is loaded, seam goes through all the page links and instantiate seam components referenced in those pages, it then adds url parameters (specified in page.xml file) to those links.
Both of these features should be option: auto Instantiation of seam components referenced in jsf pages and appending parameters to the link on jsf page.
I have menu with about 40 links to jsf pages: everytime my page refreshes all the seam components in those 40+ pages get instantiated and all think get appened with parameters specified in page.xml files.

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3480) s:link with propagation="none" linked to action with @Begin fails (intermittently) with conversation-required="true"

s:link with propagation="none" linked to action with @Begin fails (intermittently) with conversation-required="true"
---------------------------------------------------------------------------------------------------------------------
Key: JBSEAM-3480

Project: Seam
Issue Type: Bug
Reporter: Francisco Jose Peredo Noguez
You can not call a s:link with propagation="none" linked to an action with @Begin from a page with conversation-required="true" to a page with conversation-required="true" because it will redirect you to the no-conversation-view-id. (And I think it shouldn't do that, it should allow you to reach the page you originally meant to reach, because the action has a @Begin and it should consider that)
Menu.java code:
@Name("menu")
public class Menu {
@Begin
public String goToCategoryList(){
return "/CategoryList.xhtml";
}
}
layout/menu.xhtml code:
<s:link value="Category List By Action" propagation="none" action="#{menu.goToCategoryList}"/>
And in CategoryList.page.xml

The funny thing is that this makes the menu option work intermittently:
first time works (from a page without conversation-required to a page with conversation-required)
second time does not work (from a page with conversation-required to a page with conversation-required) and it gets redirected to Blank.seam
third time works (from a page without conversation-required to a page with conversation-required)
And so on and so forth...
The big question here is, if the @Begin is not really working, why it does work the first time? because if I comment the @Begin::
Menu.java code:
@Name("menu")
public class Menu {
//@Begin <----THIS IS NOW COMMENTED
public String goToCategoryList(){
return "/CategoryList.xhtml";
}
}
Then It fails always.
