    targetvalue is not update in the bean

    Marisleivy Pelaez Newbie

      Hi, I am using Seam 2.1.1, JBoss 4.2.2, RichFaces 3.3.1, EJB 3.0, Facelets y JSF. My problem is that the rich:listshuttle component is not working, the target is always empty. My client component moves the selected component from one side to another. The problem is that my selectedItems ArrayList, in my backing bean remains empty. Here you have the code:
