Thread-safety issues on Websphere with EM-injected components
-------------------------------------------------------------
Key: JBSEAM-2893
URL: http://jira.jboss.com/jira/browse/JBSEAM-2893
Project: Seam
Issue Type: Bug
Environment: Websphere 6.1.0.13 with EJB Feature Pack on both Windows XP SP2 and Solaris 9 (SunOS 5.9)
Reporter: Eric Jung
I'm attaching an extremely simple application that demonstrates thread-safety issues with EntityManager / EntityManagerFactory in Websphere 6.1. This application has one entity bean, one session bean, and one web page.
The problem is very easy to reproduce. Just start typing "e" in the search field, which uses rich:suggestionbox, and very quickly press the search button. This results in two queries being performed simultaneously--one from the rich:suggestionbox keypress, and one from submitting the page's form. All 1000 rows of data begin with "e" so the query is slow, making it easier to create queries that execute simultaneously.
You'll get one of the following exceptions if you time things right (this isn't difficult, just hit the search button very quickly--if you're too slow, both queries will succeed without error):
"javax.ejb.ConcurrentAccessException: TX_METHOD_READY: wrong transaction"
or
"java.lang.IllegalStateException: could not acquire lock on @Synchronized component: memberSearch"
I've tried this EAR with both Hibernate and OpenJPA as persistence providers, and switched databases between Apache Derby and DB2. In all four permutations, I get the exact same exceptions. That should rule out any JDBC driver or JPA implementation issues.
I suspect this problem is related to the issue mentioned in this blog post by Sahoo (a Sun engineer): http://weblogs.java.net/blog/ss141213/archive/2005/12/dont_use_persis_1.html. Unfortunately, WebSphere doesn't support servlets 2.5 so <persistence-context-ref/> isn't available in web.xml. I tried the approach he discusses in "Application Managed Entity Manager", but it hasn't yet worked.
You can download a pre-built EAR (with source code included) at http://www.mediafire.com/?tlxxgaj4qtm, but I'll be attaching source code and configuration files here, too (can't attach the EAR directly since it's 11.6 MB with all the required JARs).

Tried google chrome beta and the booking example throws the exception below when clicking on a hotel listing to book. Note this worked fin in firefox I have not checked 2.1. Also the UI, chatroom, and dvdstore all seemed to work fine with Chrome.

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2449) The capturedView stuff doesn't support capturing the parameters emitted by s:link

The capturedView stuff doesn't support capturing the parameters emitted by s:link
---------------------------------------------------------------------------------
Key: JBSEAM-2449
URL: http://jira.jboss.com/jira/browse/JBSEAM-2449
Project: JBoss Seam
Issue Type: Bug
Affects Versions: 2.0.0.GA
Environment: Windows XP
JBoss 4.2.2 GA
Seam 2.0.0 GA
RichFaces 3.1.2 GA
Facelets 1.1.13
Reporter: Andrew Elegante
I have a page with an s:link in it like so
<s:link id="newFeeProduct" value="[#{feesNav.createNewFeeProduct}]" view="/fees/feeProduct/wizard/step1.xhtml"
action="#{feeProductWizard.startNewWizard()}" propogation="begin" />
In my pages.xml I have the following:
<page view-id="/fees/feeProduct/wizard/step1.xhtml" login-required="true" >
</page>
In my components.xml I have the following:
<event type="org.jboss.seam.notLoggedIn">
<action execute="#{redirect.captureCurrentView}"/>
</event>
<event type="org.jboss.seam.postAuthenticate">
<action execute="#{redirect.returnToCapturedView}"/>
</event>
It is possible that a user could click the link without having logged in which redirects to the login page. After logging in the redirect link retains the cid but loses the actionMethod param.

Update documentation for new Entity Security with JPA behaviour
---------------------------------------------------------------
Key: JBSEAM-3446
URL: https://jira.jboss.org/jira/browse/JBSEAM-3446
Project: Seam
Issue Type: Bug
Components: Documentation Issues
Affects Versions: 2.1.0.BETA1
Reporter: Mike Pettypiece
I've noticed that the behaviour of Entity security with JPA has changed in Seam 2.1. Previously in Seam 2.0 the following Rule could be used:
rule CheckUserPermission
when
c: PermissionCheck( target == "user" )
Role( name == "admin" )
then
c.grant();
end;
However in Seam 2.1 "target" is the actual entity instance rather than the Seam component name of the entity so the rule needs to be updated as follows:
rule CheckUserPermission
when
user: User()
c: PermissionCheck( target == user )
Role( name == "admin" )
then
c.grant();
end;
The documentation should be updated to note this.
