Answer 1

StaleElementReferenceException usually happens when you are dealing with list of WebElement and before you work with your element your page is refreshed or moved back.

e.g.

List<WebElement> allElements = driver.findElements(By.xpath("/your/xpath/here"));

Now you are doing some operation in loop

for(WebElement element : allElements)

{

//some operation which makes page refresh or change

}

in above case during second iteration or next iteration, you will face StaleElementReferenceException.

To avoid that you should do as below.

for(WebElement element: allElements){

//some operation which makes page refresh or change

allElements = driver.findElements(By.xpath("/your/xpath/here"));

}

If above goes into loop you can even try below.

for(int i=0;i<allElements.size() ; i++){

element = allElements(i);

//some operation which makes page refresh or change

allElements = driver.findElements(By.xpath("/your/xpath/here"));

}

Hope that helps.
