> 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 at bo.dy</m:from>
> 		<m:to name="Marcus">your.own at 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.
