    Seam pdf problems

    Luis Soler Newbie

      Hi,


      I am generating a pdf document and everything seems to work correctly until anyone tries to log in (logging in succesfully or not doesn't make a difference). From that moment I get the following error:


      11:39:54,824 ERROR [lifecycle] JSF1054: (Phase ID: RESTORE_VIEW 1, View ID: ) Exception thrown during phase execution: javax.faces.event.PhaseEvent[source=com.sun.faces.lifecycle.LifecycleImpl@1254e47]

      I am using Seam 2.1.1 and Jboss 4.2.3


      I try to generate the document with the following xhtml (this is a simplee version for debugging):



      <p:document xmlns:p="http://jboss.com/products/seam/pdf"
                  pageSize="A4"
                  margins="15 15 0 15">

      I don't think it is a problem with missing libraries because the pdf gets correctly generated just after the server is launched. I am using a Flex client with flamingo 1.7.1 and this method used to authenticate a user:


      public static boolean login(final Identity identity, 
                                    final String username, 
                                    final String password) 
           throws StaleSessionException {
           
           try {
                //If the user is trying to log in but are already logged in,
                //we need to log them out first
                if (identity.isLoggedIn()) {
                     
                     // Calling logout will mark the current session for invalidation,
                     // so performing a subsequent login is pointless.
                     identity.logout();               
                     throw new StaleSessionException();
                }
                final Credentials credentials = identity.getCredentials();
                credentials.setUsername(username);
                credentials.setPassword(EncryptionUtils.hash(password));
                identity.login();               
                return identity.isLoggedIn();
           }
           catch (EncryptionException ex) {
                return false;
           }
      }



      Any help would be much appreciated, thanks in advance.
