2014-06-02 Created By BaoXinjian

一、摘要

实现OAF的删除功能delete

二、案例

需求：实现删除功能

1. 建立Delete按钮的连接

2. 修改VO，增加按钮

3. 在SearchInvoiceCO.java中添加如下方法

4. 在InvoiceAM中添加如下方法

三、案例实现

1. 建立Delete按钮的连接

2. 修改VO，增加按钮

3. 在SearchInvoiceCO.java中添加如下方法

 1 public void processFormRequest(OAPageContext pageContext,OAWebBean webBean) {
 2 
 3     super.processFormRequest(pageContext, webBean);
 4 
 5     /**按下删除发票Button，触发AM中的AmDeleteInvoice方法**/
 6 
 7     if ("delete".equals(pageContext.getParameter(EVENT_PARAM))) {
 8 
 9         OAApplicationModule am = pageContext.getApplicationModule(webBean);
10 
11         String InvoiceId = pageContext.getParameter("InvoiceId");
12 
13         Serializable[] parameters = { InvoiceId };
14 
15         am.invokeMethod("AmDeleteInvoice", parameters);
16 
17     }
18 
19 }

4. 在InvoiceAM中添加如下方法

 1 /**删除Invoice**/
 2 
 3 public void AmDeleteInvoice(String InvoiceId) {
 4 
 5     int InvoiceIdToDelete = Integer.parseInt(InvoiceId);
 6 
 7     OAViewObject vo = (OAViewObject)getInvoiceSummaryVO1();
 8 
 9     InvoiceSummaryVORowImpl row = null;
10 
11     int fetchRowCount = vo.getFetchedRowCount();
12 
13     System.out.print("bxj_count" + fetchRowCount);
14 
15     RowSetIterator deleteIter = vo.createRowSetIterator("deleteIter");
16 
17     if (fetchRowCount > 0) {
18 
19         deleteIter.setRangeStart(0);
20 
21         deleteIter.setRangeSize(fetchRowCount);
22 
23         for (int i = 0; i < fetchRowCount; i++) {
24 
25             row = (InvoiceSummaryVORowImpl)deleteIter.getRowAtRangeIndex(i);
26 
27             Number primaryKey;
28 
29             primaryKey = row.getInvoiceId();
30 
31             if (primaryKey.compareTo(InvoiceIdToDelete) == 0) {
32 
33                 row.remove();
34 
35                 getTransaction().commit();
36 
37                 break;
38 
39             }
40 
41         }
42 
43     }
44 
45     deleteIter.closeRowSetIterator();
46 
47 }

Thanks and Regards
