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
5. 在UpdateInvoiceCO.java中添加如下方法
6. 在InvoiceAM中添加如下方法
7. 在InvocieUpdateVO中添加如下方法
8. 在UpdateInvoiceCO.java中添加如下方法
9. 在InvoiceAM中添加如下方法
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,20 21 true,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
1 /**修改Invoice，将资料做Commit**/2 3 public void AmUpdateApply() {4 5 getTransaction().commit();6 7 }
