列表的Selenium中的“StaleElementReferenceException”

Question

请你提出一些解决这个问题的方法好吗？谢谢

List<WebElement> orderID = new ArrayList<WebElement>();
List<WebElement> statusID = new ArrayList<WebElement>();

public void OrderandReleases()     
{
orderID = outboxpage.findtable(orderID);
util.pause("1");
statusID = outboxpage.findordernumber(statusID, orderID);
}

public List<WebElement> findOrderID(List<WebElement> orderID) {
WebElement table = driver.findElement(By.id("_kod7c3"));      
List<WebElement> allRows = table.findElements(By.tagName("tr"));

//And iterate over them, getting the cells 
for (int i = 1; i < allRows.size(); i++) {
 List<WebElement> alltd = allRows.get(i).findElements(By.tagName("td"));
                for (int j = 0; j < alltd.size(); j++) {
                    if (j == 1) {
                        orderID.add(alltd.get(j));
                        continue;
                    }
                }
            }
              return orderID;
}

public List<WebElement> clickonIndividualOrderID(List<WebElement> 
statusID,List<WebElement> orderID){
    for (int i = 0; i < orderID.size(); i++) {  
    WebElement table = driver.findElement(By.id("_kod7c3")); 
        if (table.isDisplayed()) {
            System.out.println("Clicking on 
order="+orderID.get(i).getText()); -> //first time it will run fine , second time when it loops back it will thow the execption StaleElementReferenceException here
            orderID.get(i).click(); -> //it is clicking on a order link and it will take me to next page
            driver.findElement(By.id("_jxndro")).click();

            WebElement table2 = driver.findElement(By.xpath("//*
[@id=\"_mfb\"]"));  
            List<WebElement> allRows2 = 
table2.findElements(By.tagName("tr"));

            String col = "";
            for (int j = 1; j < allRows2.size(); j++) {
                List<WebElement> alltd2 = 
allRows2.get(j).findElements(By.tagName("td"));
                int flag = 0;
                for (int k = 0; k < alltd2.size(); k++) {
                    col = alltd2.get(k).getText().toString().trim();
                    System.out.println(col);
                    if (col.equals("Failed")||col.contains("FE-")) {
                        statusID.add(alltd2.get(++k));
                        driver.findElement(By.id("_uvsub")).click(); --> // it will take me back to the first page
                        flag =1;
                        break;
                    }
                }
                 if(flag==1)
                        break;
            }
        }
    }
    return statusID;
}
