二、分步解析

1.建立SearchInvoicePG对应的Create按钮以跳转到Create页面

    

 

2. SearchInvoiceCO.java中添加如下方法

public void processFormRequest(OAPageContext pageContext,OAWebBean webBean) { 

    super.processFormRequest(pageContext, webBean);

    /**按下创建发票Button，页面跳转至创建发票页面**/

    if (pageContext.getParameter("Create") != null) {

        pageContext.setForwardURL("OA.jsp?page=/oracle/apps/bxj/ap/invoice/webui/CreateInvoicePG",

                                  null,

                                  OAWebBeanConstants.KEEP_MENU_CONTEXT,

                                  null, null, true,

                                  OAWebBeanConstants.ADD_BREAD_CRUMB_YES,

                                  OAWebBeanConstants.IGNORE_MESSAGES);

    }

}

 

 

3. 建立CreateInvoicePG，设定Button Region和Main Region

    

 

4. CreateInvoiceCO.java中添加如下方法

public void processRequest(OAPageContext pageContext, OAWebBean webBean) {

    super.processRequest(pageContext, webBean);

    /**初始化页面，调用创建Row的方式**/

    if (!pageContext.isBackNavigationFired(false)) {

        TransactionUnitHelper.startTransactionUnit(pageContext, "CreateInvoiceTxn");

        if (!pageContext.isFormSubmission()) {

            OAApplicationModule am = pageContext.getApplicationModule(webBean);

            am.invokeMethod("AmCreateInvoice");

        }

    } else {

        if (!TransactionUnitHelper.isTransactionUnitInProgress(pageContext,"CreateInvoiceTxn",true)) {

            OADialogPage dialogPage = new OADialogPage(NAVIGATION_ERROR);

            pageContext.redirectToDialogPage(dialogPage);

        }

    }

    OAApplicationModule am = pageContext.getApplicationModule(webBean);

    am.invokeMethod("AmCreateInvoice", null);

}

 
 

5. 在InvoiceAM中添加如下方法

/**创建Invoice，初始化页面创建Row以存放资料**/

public void AmCreateInvoice() {

    OAViewObject vo = (OAViewObject)getInvoiceCreateVO1();

    vo.setMaxFetchSize(0);

    vo.executeQuery();

    Row row = vo.createRow();

    vo.insertRow(row);

    row.setNewRowState(Row.STATUS_INITIALIZED);

}

 

 

6. CreateInvoiceCO.java中添加如下方法

public void processFormRequest(OAPageContext pageContext,OAWebBean webBean) {

    super.processFormRequest(pageContext, webBean);

    /**按下确定Button后，调用创建Invoice的AM 方法**/

    OAApplicationModule am = pageContext.getApplicationModule(webBean);

    if (pageContext.getParameter("Apply") != null) {

        OAViewObject vo = (OAViewObject)am.findViewObject("CreateInvoiceVO1");

        am.invokeMethod("AmCreateApply", null);

        TransactionUnitHelper.endTransactionUnit(pageContext,"CreateInvoiceTxn");

        pageContext.forwardImmediately("OA.jsp?page=/oracle/apps/bxj/ap/invoice/webui/SearchInvoicePG",

                                       null,

                                       OAWebBeanConstants.KEEP_MENU_CONTEXT,

                                       null, null, true,

                                       OAWebBeanConstants.ADD_BREAD_CRUMB_NO);

    } else if (pageContext.getParameter("Cancel") != null) {

        am.invokeMethod("AmCreateRollback", null);

        TransactionUnitHelper.endTransactionUnit(pageContext, "CreateInvoiceTxn");

        pageContext.forwardImmediately("OA.jsp?page=/oracle/apps/bxj/ap/invoice/webui/SearchInvoicePG",

                                       null,

                                       OAWebBeanConstants.KEEP_MENU_CONTEXT,

                                       null,null,true,

                                       OAWebBeanConstants.ADD_BREAD_CRUMB_NO);

    }
}

 

 

7. 在InvoiceAM中添加如下方法

/**创建Invoice，将资料做Commit**/

public void AmCreateApply() {

    getTransaction().commit();

}

 

 

8. SearchInvoiceCO.java中添加如下方法

public void processRequest(OAPageContext pageContext, OAWebBean webBean) {

    super.processRequest(pageContext, webBean);

    /**从创建Invoice页面跳转至查询Invoice页面时，检查Create Invoice资料是否被Commit**/

    OAApplicationModule am = pageContext.getApplicationModule(webBean);

    if (TransactionUnitHelper.isTransactionUnitInProgress(pageContext,"CreateInvoice",false)) {

        am.invokeMethod("AmCreateRollback");

        TransactionUnitHelper.endTransactionUnit(pageContext, "CreateInvoiceTxn");

    }

}
