[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-2493) Problems with faces Renderer when used simultaneously from different threads

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 Priority: Minor Fix For: 2.0.2.GA, 2.1.0.GA 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.
