项目中表之间关联关系特别多，比如三个表中A,B,C C作为主表，A，B作为从表，有时候C表需要创建数据时，同时需要创建A，B两个表的数据，这种情况下，使用Wizard样式会更加友好。
以Goods__c表和Goods_Vendor__c表为例，Goods__c为主表，Goods_Vendor__c为从表。新建Goods__c记录以后同时要创建其相关的数据。
表结构关系如下：
代码：
1.GoodsHelper:封装获取goods的列表方法
1 public without sharing class GoodsHelper {
2
3 public static final String BASE_GOODS_QUERY = 'SELECT CreatedById, CreatedDate, IsDeleted,' +
4 ' Goods_Code_Unique__c, Name, GoodsPicture__c, GoodsBrand__c, GoodsCostPrice__c,' +
5 ' GoodsDescribe__c, GoodsName__c, GoodsPrice__c, GoodsProfit__c, Is_Draft__c,' +
6 ' LastModifiedById, LastModifiedDate, No__c, OwnerId, Id, RecordTypeId,' +
7 ' Status__c, SystemModstamp' +
8 ' FROM Goods__c where IsDeleted = false';
9 public static final String BASE_GOODS_COUNT_QUERY = 'SELECT count() from Goods__c where IsDeleted = false';
10 public static MyPaginationEnhancement getGoodsList(String goodsName,String goodsBrand,MyPaginationEnhancement pagination) {
11 String queryCondition= '';
12 String orderBy ='';
13 if(goodsName != null) {
14 queryCondition += ' and GoodsName__c like %\'' + goodsName + '%\'';
15 }
16 if(goodsBrand != null) {
17 queryCondition += ' and GoodsBrand__c = :goodsBrand';
18 }
19 orderBy = ' order by createddate';
20
21 pagination.getQueryResult(BASE_GOODS_COUNT_QUERY,BASE_GOODS_QUERY,queryCondition,null,orderBy);
22 return pagination;
23 }
24 }2.GoodsListController:Goods列表Controller
1 public with sharing class GoodsListController {
2 public Map<String,String> parameters;

22 }
23
24 public MyPaginationEnhancement resultPagination{
25 get{
26 if(pagination ==null){
27 pagination =new MyPaginationEnhancement();
28 }
29 return pagination;

2.点击编辑，如果点击新建其他内容均为空，此处只显示编辑
3.点击next进入vendor页面
4.total页面
5.点击save以后，成功则跳转到list页面，失败则显示失败ERROR
失败情况：
成功情况：
总结：Wizard适用于新建数据时创建一套级联数据情况，篇中step1-3之间的跳转均使用转发方式，而不是重定向(ref.setRedirect(true))，原因为：三个页面绑定了同一个controller，转发方式第一次进入走构造函数，以后均不在走构造函数，而重定向需要每次都走构造函数。如果使用重定向，则前一页修改的数据重定向以后在回此页面，修改的数据便会回滚到以前的状态。有错误的地方欢迎指正，有问题欢迎留言。
