    <p>I have not been able to find a solution to this problem and my post to the Seam forum has gone unanswered. I am hope someone here can help.</p> <p>I am a noob working with Seam, so I am sure I am just doing something stupid. Any help anyone can give me would be greatly appreciated... I have wasted hours and gotten nowhere. I used the jboss tools to generate a seam project in eclipse. The tool took pre-created JPA entities and created a basic webapp. My first step was to add a registration page so that I can create some users and login using database authentication (I set this up, but will test it once the registration page works). I used the seam-booking example to guide me (basically integrating the form stuff plus additional fields into the view of the seam-gen app). When I test the registration page, I get NullPointerExceptions for all of the injected fields. I have looked through the entire seam-booking example, scoured the web looking at examples, and quickly read through some sections of a book and I do not see where there is any additional configuration information needed. What in the world am I doing wrong? Please help!!!</p> <p>I am using JBoss Server (community edition) 5.1.0GA and Seam 2.2.0GA. </p> <p>If you need any more information than what I am posting, please let me know. Thanks to all ahead of time for your help!! </p> <p>Stateful EJB: </p> <pre><code>@Stateful @Scope(EVENT) @Name("register") public class RegisterAction implements Register { @In private User user; @PersistenceContext private EntityManager entityManager;

if (existing.size() == 0) { entityManager.persist(user); facesMessages .add("Successfully registered as #{user.userName}"); registered = true; } else { facesMessages.addToControl("userName", "Username #{user.userName} already exists"); } } else { facesMessages.addToControl("verify", "Re-enter your password"); verify = null; } } public void invalid() { facesMessages.add("Please try again"); } public boolean isRegistered() { return registered;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
