Problems with faces Renderer when used simultaneously from different threads
----------------------------------------------------------------------------
Key: JBSEAM-2493
URL: http://jira.jboss.com/jira/browse/JBSEAM-2493
Project: JBoss Seam
Issue Type: Bug
Components: Mail
Affects Versions: 2.0.0.GA
Environment: Seam-App in JBoss 4.2
Properly configure mail-service
Reporter: Marcus Schmidke
Assigned To: Pete Muir
When creating multiple renderers in different threads and using them simultaneously, there
are problems with JSF variables (for example in ui:repeat)
Create the following classes:
@Name("seamMailBug")
@Scope(ScopeType.EVENT)
public class SeamMailBug {
@In
private Renderer renderer;
@Asynchronous
public void send(List<String> asList) {
Context c = Contexts.getEventContext();
c.set("l", asList);
renderer.render("/seamMailBug.xhtml");
}
}
@Name("seamMailBug1")
@Scope(ScopeType.EVENT)
public class SeamMailBug1 {
public void send() {
SeamMailBug smb = (SeamMailBug) Component
.getInstance(SeamMailBug.class);
smb.send(Arrays.asList(new String[] { "L2-1" }));
smb.send(Arrays.asList(new String[] { "L1-1", "L1-2",
"L1-3" }));
}
}
Create the mail template seamMailBug.xhtml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<ui:repeat xmlns="http://www.w3.org/1999/xhtml"
xmlns:m="http://jboss.com/products/seam/mail"
xmlns:ui="http://java.sun.com/jsf/facelets"
value="#{l}" var="v"
<m:message>
<m:from>some@bo.dy</m:from>
<m:to name="Marcus">your.own@email.address</m:to>
<m:body>
Guten Tag! #{v}
</m:body>
</m:message>
</ui:repeat>
And in pages.xml:
<page view-id="/seambug.xhtml" action="#{seamMailBug1.send}"/>
Start the server and get the URL: http://..../.../seambug.seam
One should expect 4 mails being sent, containing the strings L1-1, L1-2, L1-3 and L2-1.
The number of mails actually sent will be correct, but carefully verify the strings being
sent.
You will see that the "v" iterator variable is the same used from both threads.
