PrimeFaces ManyCheckbox ArrayList未在模式对话框中更新[重复]

Question

我有一个模式对话框，其中用户可以根据另一个用户选择和取消选择角色，然后将其提交到数据库以进行更新。

>

加载应用程序

数据库中有一个角色为“admin”的用户

我尝试编辑这个用户，对话框打开，“管理”复选框被选中。

<p:dialog header="Editing User ID: #{usersView.viewUser}" id="editUserDialog" widgetVar="editUserDialog" modal="true" appendTo="@(body)">
    <h:form id="editUserForm">
        <p:selectManyCheckbox id="roleSelect" value="#{usersView.selectedRoles}" layout="grid" columns="3">
            <f:selectItems value="#{rolesView.roles}" var="role" itemLabel="#{role.name}" itemValue="#{role.name}" />
        </p:selectManyCheckbox>
        <p:separator />
        <p:commandButton process="@this" update=":form:tabs:adminView:userTable:userRoleOutput" value="Submit" id="EditUserSubmitButton" actionListener="#{usersView.editUserRole}" oncomplete="PF('editUserDialog').hide();" />
    </h:form>
</p:dialog>

@ManagedBean(name="usersView", eager=true)
@ApplicationScoped

private ArrayList<String> selectedRoles;

public Arraylist<String> getSelectedRoles()
{
    return this.selectedRoles;
}

public void setSelectedRoles(ArrayList<String> roles)
{
    this.selectedRoles = roles;
}

public void editUserRole(ActionEvent actionEvent)
{
    // This method literally just loops through all users and matches the one we're looking at
    User user = findUser();

    if (user != null)
    {
        // gives user checked roles in database and local session
        addSelectedRoles(user);

        ArrayList<String> rolesToRemove = user.getRoleNames();
        rolesToRemove.removeAll(selectedRoles);

        // removes user unchecked roles in database and local session
        removeSelectedRoles(user, rolesToRemove);
    }

    else
    {
        // Handle exception...
    }
}

Answer 1

我通过删除process=“@this”来解决问题，现在ArrayList正在更新。

process=“@this”表示commandLink的当前组件，因此它没有更新。
