Selenium: How to avoid StaleElementReferenceException when looping through a set of elements?

Question

I have a page that contains a bunch of tables. I loop through the tables in the outer loop and then loop through each row in the table in the inner loop. It all works fine

Answer 1

Well after tearing my hair out for a day, I finally realized what was happening. It should have been obvious to me. When the "Next" button is clicked, it takes some time for the new page to load. By simply adding a delay, the new DOM is loaded and processing begins on it, not again on the previous one!

            driver.findElement(By.xpath(".//*[@class='PageRight']")).click();
        try {
            Thread.sleep(4000); //provide some time for the page to load before processing it
        } catch (InterruptedException ex) {
            Logger.getLogger(RealAuction.class.getName()).log(Level.SEVERE, null, ex);
        }

Now it runs to completion with no StaleElementReferenceException.
