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
public without sharing class GoodsHelper {
public static final String BASE_GOODS_QUERY = 'SELECT CreatedById, CreatedDate, IsDeleted,' +
' Goods_Code_Unique__c, Name, GoodsPicture__c, GoodsBrand__c, GoodsCostPrice__c,' +
' GoodsDescribe__c, GoodsName__c, GoodsPrice__c, GoodsProfit__c, Is_Draft__c,' +
' LastModifiedById, LastModifiedDate, No__c, OwnerId, Id, RecordTypeId,' +
' Status__c, SystemModstamp' +
' FROM Goods__c where IsDeleted = false';
public static final String BASE_GOODS_COUNT_QUERY = 'SELECT count() from Goods__c where IsDeleted = false';
public static MyPaginationEnhancement getGoodsList(String goodsName,String goodsBrand,MyPaginationEnhancement pagination) {
String queryCondition= '';
String orderBy ='';
if(goodsName != null) {
queryCondition += ' and GoodsName__c like %\'' + goodsName + '%\'';
}
if(goodsBrand != null) {
queryCondition += ' and GoodsBrand__c = :goodsBrand';
}
orderBy = ' order by createddate';
pagination.getQueryResult(BASE_GOODS_COUNT_QUERY,BASE_GOODS_QUERY,queryCondition,null,orderBy);
return pagination;
}
}
2.GoodsListController:Goods列表Controller
public with sharing class GoodsListController {
public Map<String,String> parameters;
public GoodsListController() {
parameters=ApexPages.currentPage().getParameters();
init();
}
public MyPaginationEnhancement pagination = new MyPaginationEnhancement();
public String goodsName{get;set;}
public String goodsBrand{get;set;}
public void init() {
queryByCondition();
}
public void queryByCondition() {
GoodsHelper.getGoodsList(goodsName,goodsBrand,pagination);
}
public MyPaginationEnhancement resultPagination{
get{
if(pagination ==null){
pagination =new MyPaginationEnhancement();
}
return pagination;
}
set;
}
public List<Goods__c> resultList{
get{
if(pagination==null || pagination.resultList==null){
return new List<Goods__c>();
}
return pagination.resultList;
}
set;
}
public PageReference newGoods() {
return Page.detailGoods;
}
public void firstPage() {
pagination.first();
queryByCondition();
}
public void lastPage() {
pagination.last();
queryByCondition();
}
public void previousPage() {
pagination.previous();
queryByCondition();
}
public void nextPage() {
pagination.next();
queryByCondition();
}
}

4.GoodsDetailController:此类中封装了Wizard的相关方式，Wizard的相关跳转均为转发方式。

if(isEditView == null) {

5.detailGoods.page:商品信息详情页面

效果展示：
1.商品列表
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。
