    Given final block not properly padded

    Rand Asin Novice

      I have a simple page with some menuItems like the demo page.  I noticed the following steps cause error: Given final block not properly padded

       

      1. Load my page (i.e .menu.faces)
      2. restart JBoss or let my session time out
      3. Click on a menu item without reloading menu.faces

       

      I get

      I noticed the similar issue on RichFaces Online Demo if I leave the browser open for a long time and then try to interact with the menu demo.  Looks like it's trying to restore state, but the session no longer exists.  I don't understand why since none of my beans are session scope.  Are the menu components stateful?  How do I get around this issue?

       

      Any thoughts would be appreciated.  Thanks.

          That fixed the BadPaddingException, but I am getting

          I think my core issue remains that view is stateful when I don't want it to be.  How should I design my view so it's not stateful?  My beans are request scope only, what else should I look for?

           

          BTW where can I change my JBoss Community account password?  Got a notification from JBoss the other day to reset my password, now I can't find the place to change my password.  Any help would be appreciated.

            In JSF views are stateful, unless you've set it to "transient".
