Weld creating multiple instances of @SessionScoped beans
timpii Oct 13, 2011 3:00 AMUsing JbossAS 7.0.2 with CDI. The problem is that for every reference from an xhtml file to a @SessionScoped @Named bean a new instance of the bean is being created. I have run it within the debugger and watched the object ids increment. In moving to a new page, new instances are also created. I created my POM from the jboss 7 login example, (after finding out an EAR flat would not work), and added from there. The POM is :
