Question

我正在overlayPanel中编写SelectOneMenu。问题是所选值在bean中始终为null。没有调用setter方法，所以我认为当我选择一个项目时不会提交SelectOneMenu。

这是我的页面：

    <p:overlayPanel id="OverLayPanelNewRole" for="buttonAddRole">

                <p:selectOneMenu id="SelectOneMenuRoles" value="#{userSettingBean.selectedRole}" 
                onchange="submit()" immediate="true">

                   <f:selectItems value="#{userSettingBean.roleList}" var="role" itemLabel="#{role.NAME}" style="width:100%"/>

               </p:selectOneMenu>       
    </p:overlayPanel>

My Managed Bean：

@ManagedBean(name = "userSettingBean")
@SessionScoped
public class UserSettingBean implements Serializable {

    private static final long serialVersionUID = -7579402702068562565L;

    @ManagedProperty(value= "#{roleServiceImpl}")
    private RoleService roleService; 

    private List<Role> roleList;
    private Role selectedRole;

    @PostConstruct
    public void init(){

        //init Roles for selection in overlayPanel
        roleList=roleService.findAllRole();
    }

    public RoleService getRoleService() {
        return roleService;
    }

    public void setRoleService(RoleService roleService) {
        this.roleService = roleService;
    }

    public List<Role> getRoleList() {
        return roleList;
    }

    public void setRoleList(List<Role> roleList) {
        this.roleList = roleList;
    }

    public Role getSelectedRole() {
        return selectedRole;
    }

    public void setSelectedRole(Role selectedRole) {
        this.selectedRole = selectedRole;
    }

有人可以帮我解决这个问题吗？

总结评论，删除immediate =“true”纠正了这种情况下的问题。但是，使用onchange =“submit（）”应替换为＆lt; f：ajax＆gt;如果使用jsf 2.0+。请参阅此处的相关文章：

h:selectOneMenu onchange="submit()" immediate="true" does not skip validation of other inputs
