[JBoss Seam] - Re: please help me out of this problem
by fernando_jmt
I would use a @Factory.
Java:
|
| @Stateful
| @Name("userRegister")
| @Scope(ScopeType.SESSION)
| public class UserRegisterAction implements UserRegister {
|
| private Log logger = LogFactory.getLog(UserRegisterAction.class);
|
| private User user;
| private String selectedUsername = "0";
|
|
|
| @Factory(value = "user", scope = ScopeType.STATELESS)
| public User initUser() {
| if(selectedUsername.equals("0")){
| logger.debug("new user");
| user = new User();
| }else{
| logger.debug("edit:"+ selectedUsername);
| user = userDao.load(selectedUsername);
| logger.debug("test:"+ user.getUsername());
| }
| return user;
| }
|
| public void userListValueChanged(ValueChangeEvent event) {
|
| try {
| selectedUsername = (String) event.getNewValue();
|
| } catch (Exception e) {
| e.printStackTrace();
| }
| }
|
| }
|
|
Facelet:
| <h:panelGroup id="exportUser">
| <h:outputLabel id="Username"
| <h:inputText value=#{user.username}/>
|
| <h:outputLabel id="Whatever"
| <h:inputText value=#{user.whateverProperty}/>
|
| <h:outputLabel id="userL" value="#{bundle['userDefination.group']}" for="groupMenu" />
| <t:selectOneMenu id="userMenu" required="false" value="#{userRegister.selectedUsername}"
| valueChangeListener="#{userRegister.userListValueChanged}" onchange="submit(this)" >
| <f:selectItem itemLabel="New User ..." itemValue="0" />
| <f:selectItems id="userList" value="#{userRegister.allUsers}" />
| </t:selectOneMenu>
| </h:panelGroup>
|
