一、摘要

实现OAF修改功能Update

 

二、案例

需求：实现修改功能

1. 建立Update按钮的连接

2. 设定触发事件为FireAction

3. 在SearchInvoiceCO.java中添加如下方法

4. 建立UpdateInvoicePG

三、案例实现

1. 建立Update的连接

    

 

2. 设定触发事件为FireAction

    

 

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     /**按下更改发票Button，触发AM中的AmUpdateInvocie方法**/
 6 
 7     if ("update".equals(pageContext.getParameter(EVENT_PARAM))) {
 8 
 9         OAApplicationModule am = pageContext.getApplicationModule(webBean);
10 
11         pageContext.setForwardURL("OA.jsp?page=/oracle/apps/bxj/ap/invoice/webui/UpdateInvoicePG",
12 
13                                    null,
14 
15                                    OAWebBeanConstants.KEEP_MENU_CONTEXT,
16 
17                                    null,
18 
19                                    null,

22 
23                                    OAWebBeanConstants.ADD_BREAD_CRUMB_NO,
24 
25                                    OAWebBeanConstants.IGNORE_MESSAGES);
26 
27     }
28 
29 }

 

4. 建立UpdateInvoicePG

    

 

5. 在UpdateInvoiceCO.java中添加如下方法

 1 public void processRequest(OAPageContext pageContext, OAWebBean webBean) {
 2 
 3     super.processRequest(pageContext, webBean);
 4 
 5     /**从SearchInvoice调转至UpdateInvoice，对修改发票页面初始化**/
 6 
 7     String InvoiceId = pageContext.getParameter("InvoiceId");
 8 
 9     if (!pageContext.isBackNavigationFired(false)) {
10 
11         TransactionUnitHelper.startTransactionUnit(pageContext,"UpdateInvoiceTxn");
12 
13         if (!pageContext.isFormSubmission()) {
14 
15             Serializable[] params = { InvoiceId };
16 
17             OAApplicationModule am = pageContext.getApplicationModule(webBean);
18 
19             am.invokeMethod("AmInitUpdateInvoice",params);
20 
21         }
22 
23     } else {
24 
25         if (!TransactionUnitHelper.isTransactionUnitInProgress(pageContext,"UpdateInvoiceTxn",true)) {
26 
27             OADialogPage dialogPage = new OADialogPage(NAVIGATION_ERROR);
28 
29             pageContext.redirectToDialogPage(dialogPage);
30 
31         }
32 
33     }
34 
35 }

 

6. 在InvoiceAM中添加如下方法

 1 /**显示Invoice 明细页面**/
 2 
 3 public void AmShowInvoice(String InvoiceId){
 4 
 5     InvoiceDetailVOImpl vo = getInvoiceDetailVO1();
 6 
 7     if (vo == null) {
 8 
 9         MessageToken[] errtokens = {new MessageToken("OBJECT_NAME","InvoiceDetailVO1")};
10 
11         throw new OAException("AK","FWK_TBX_OBJECT_NOT_FOUND",errtokens);
12 
13     }
14 
15     vo.VoShowInvoice(InvoiceId);
16 
17 }

 

 

7. 在InvocieUpdateVO中添加如下方法

 1 /**从SearchInvoice页面跳转至UpdateInvoice页面，实现自动查询**/
 2 
 3 public void VoShowInvoice(String InvoiceId) {
 4 
 5     if ((InvoiceId != null) & (!("".equals(InvoiceId.trim())))) {
 6 
 7         Number Invoice_Id = null;
 8 
 9         try {
10 
11             Invoice_Id = new Number(InvoiceId);
12 
13         } catch (Exception e) {
14 
15             throw new OAException("CUX", "CUX_INVOICE_INVALID_NOTIFY_ID");
16 
17         }
18 
19         setWhereClause("INVOICE_ID = :1");
20 
21         setWhereClauseParams(null);
22 
23         setWhereClauseParam(0, Invoice_Id);
24 
25         executeQuery();
26 
27     }
28 
29 }

 

8. 在UpdateInvoiceCO.java中添加如下方法

 1 public void processFormRequest(OAPageContext pageContext,OAWebBean webBean) {
 2 
 3     super.processFormRequest(pageContext, webBean);
 4 
 5     /**按下确定Button后，调用修改Invoice的AM 方法**/
 6 
 7     OAApplicationModule am = pageContext.getApplicationModule(webBean);
 8 
 9     if (pageContext.getParameter("Apply") != null) {
10 
11         OAViewObject vo = (OAViewObject)am.findViewObject("UpdateInvoiceVO1");
12 
13         am.invokeMethod("AmUpdateApply", null);
14 
15         TransactionUnitHelper.endTransactionUnit(pageContext,"UpdateInvoiceTxn");
16 
17         pageContext.forwardImmediately("OA.jsp?page=/oracle/apps/bxj/ap/invoice/webui/SearchInvoicePG",
18 
19                                         null,
20 
21                                         OAWebBeanConstants.KEEP_MENU_CONTEXT,
22 
23                                         null, null, true,
24 
25                                         OAWebBeanConstants.ADD_BREAD_CRUMB_NO);
26 
27     } else if (pageContext.getParameter("Cancel") != null) {
28 
29         am.invokeMethod("AmCreateRollback", null);
30 
31         TransactionUnitHelper.endTransactionUnit(pageContext, "CreateInvoiceTxn");
32 
33         pageContext.forwardImmediately("OA.jsp?page=/oracle/apps/bxj/ap/invoice/webui/SearchInvoicePG", null,
34 
35                                        OAWebBeanConstants.KEEP_MENU_CONTEXT,
36 
37                                        null,null,true,
38 
39                                        OAWebBeanConstants.ADD_BREAD_CRUMB_NO);
40 
41     }
42 
43 }

 

9. 在InvoiceAM中添加如下方法
