I am currently experiencing a few problems with submitting form data. I must be missing something some where. I am using Seam 2.0 BETA 1, JBoss AS 4.2 and Kubuntu 64 The problem is that I am getting the following errors when I submit the form. The action to display a simple list of users works correctly using the name provided to seam. Did I miss something when setting up my class methods? Jboss Errors: | Caused by: javax.ejb.EJBTransactionRolledbackException: Could not get property value... | | Caused by: java.lang.IllegalArgumentException: Invoking setPassword with wrong parameters... | I have setup the entity as follows | import ... | | @Entity | @Table(name = "Users") | @Name("user") | public class UserImpl implements User | {... | Here is the setPassword method | @NotNull | @Length(min=3, max=15) | public void setPassword(String password) | { | this.password = password; | } | I have a simple form... | <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" | "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> | <ui:composition xmlns="http://www.w3.org/1999/xhtml" | xmlns:s="http://jboss.com/products/seam/taglib" | xmlns:ui="http://java.sun.com/jsf/facelets" | xmlns:f="http://java.sun.com/jsf/core" | xmlns:h="http://java.sun.com/jsf/html" | xmlns:rich="http://richfaces.ajax4jsf.org/rich" | template="/layout/template.xhtml"> | | <ui:define name="body"> | <h:form> | <table border="0"> | | <tr> | <td>Username</td> | <td><h:inputText value="#{user.userName}"/></td> | </tr> | <tr> | <td>First Name</td> | <td><h:inputText value="#{user.firstName}"/></td> | </tr> | <tr> | <td>Last Name</td> | <td><h:inputText value="#{user.lastName}"/></td> | </tr> | | <tr> | <td>Password</td> | <td><h:inputSecret value="#{user.password}"/></td> | </tr> | | </table> | <h:commandButton type="submit" value="Add User" action="#{useraction.addUser}"/> | </h:form> | | </ui:define> | </ui:composition> | The addUser method in the UserActionImpl class | public String addUser() | { | | em.persist(user); | | List existing = em.createQuery("select userName from UserImpl where userName=:userName").setParameter("userName", user.getUserName()).getResultList(); | | if (existing.size()==0) | { | em.persist(user); | //log.info("Registered new user #{user.username}"); | return "/admin/user/userlist.xhtml"; | } | else | { | FacesMessages.instance().add("User #{user.userName} already exists"); | return null; | } | } | I think I have everything setup correctly. Nothing fancy going on here just working through the basics. Any assistance would be most appreciated.
