將信息從彈出窗口傳遞到Oracle ADF上的主窗口

Question

我有一個彈出窗口顯示一個包含數據的表，我可以選擇一行，按下OK按鈕我可以檢索表中所選行的idNo。

我想要做的是將此idNo傳遞給調用彈出窗口的窗口並更新此窗口上的outputText。

有人能幫我嗎？

按鈕代碼：

按鈕的newBean類：

 public String b1_action() {
        // Add event code here...

        System.out.println("Select One Button has been Clicked");

            // Get bindings associated with the current scope, then access the one that we have assigned to our table - e.g. OpenSupportItemsIterator
            DCBindingContainer bindings =
                (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
            DCIteratorBinding dcItteratorBindings =
                bindings.findIteratorBinding("NameView1_1Iterator");

            // Get an object representing the table and what may be selected within it
            ViewObject voTableData = dcItteratorBindings.getViewObject();

            // Get selected row
            Row rowSelected = voTableData.getCurrentRow();

            // Display attriebute of row in console output - would generally be bound to a UI component like a Label and or used to call another proces
            System.out.println(rowSelected.getAttribute("IdNo"));

            setOutputText("" + rowSelected.getAttribute("IdNo") + "");
            closePopup("p1");

        return null;
    }

我想要我的函數： setOutputText() ， setOutputText()沒有實現，能夠在主窗口上更新我的outputText。

謝謝最誠摯的問候

Answer 1

將“IdNo”放在視圖或頁面流量范圍內，具體取決於您希望如何保留值。

//view scope
AdfFacesContext.getCurrentInstance().getViewScope().put("IdNo", value);

//or page flow scope
AdfFacesContext.getCurrentInstance().getPageFlowScope.put("IdNo", value);

在window bean中，為彈出對話框編寫一個監聽器：

public void dialogCloseListener(DialogEvent dialogEvent) {
    if (dialogEvent.getOutcome().equals(DialogEvent.Outcome.ok)) {
        String idNo = AdfFacesContext.getCurrentInstance().getViewScope().get("IdNo");
        //now you have the idNo, do whatever you want

    }
}

您也可以在按鈕或鏈接中使用returnListener，如本文中那樣調用彈出窗口
