org.openqa.selenium.NoSuchWindowException：无法获取浏览器

Question

我正在登录我的应用程序（IE 浏览器）。在主页上，它有消费者链接。我点击它..它将打开另一个窗口..输入消费者ID（仅必填字段）并保存。它正在被拯救。

现在如果我想查看保存的消费者。我需要关闭窗口并需要将控件转移到主页。关闭窗口后，我正在尝试driver.switchTo.defaultContent()。但它不会改变控制。返回以下错误..

例外：

Exception in thread "main" org.openqa.selenium.NoSuchWindowException: Unable to get browser (WARNING: The server did not provide any stacktrace information)

尝试在切换之前存储处理程序名称。

public static void main(String[] args) throws IOException, InterruptedException {
        // TODO Auto-generated method stub
        File file = new File("IEDriverServer.exe");
        System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
        WebDriver driver = new InternetExplorerDriver();        
        driver.get("http://xx.xxx.xxx.xx/mysuite/Login.aspx");
        driver.findElement(By.id("txtUser")).sendKeys("administrator");
        driver.findElement(By.id("txtPwd")).sendKeys("password");
        driver.findElement(By.id("cmdLogin")).click();      
        //Click Add customer (customer child window opens)
        driver.findElement(By.linkText("Add Customer")).click();

        //Store before switch    
        String  mainHandle= driver.getWindowHandle();

        driver.switchTo().window("Customer");

        //Enter Customer ID and Save
        driver.findElement(By.id("txtCode")).sendKeys("1234");
        driver.findElement(By.id("cmdPageSave")).click();
                //Close the child window
        driver.findElement(By.id("cmdPageClose")).click();
        //swith back to parent window

        driver.switchTo().window(mainHandle);

        Thread.sleep(3000);
        driver.findElement(By.linkText("All customers")).click();

    }
