i use the @Factory,but can't solve the question
my list bean generated jboss gen:
package cn.sh.guanghua.manhour.service.admin;

'admin'";

| return user;
| }
|

|

| }
| else if (this.getUser().getState() == 1) {
| list.add("lower(user.state) = #{userList.user.state}");
| }
| else {
| //do nothing
| }
| list.addAll(Arrays.asList(RESTRICTIONS));
| return list;
| }

| list.add(new SelectItem(loginUser.getId(),
loginUser.getName()));
|
| Query query = getEntityManager().createQuery("select user from
User user " +

+ " and user.id <> " + loginUser.getId());
| List<User> users = query.getResultList();
| for (User user : users) {
| list.add(new SelectItem(user.getId(), user.getName()));
| }
| return list;
| }
|
|
|
| }

my page code invoking the method:
<h:selectOneMenu id="principalId" value="#{activityList.principalId}"
onchange="javascript:document.getElementById('weekActivity').submit();">
| <f:selectItems value="#{userList.usersByManager}"/>
| </h:selectOneMenu
