How to handle StaleElementReferenceException

I have a scenario where I am attempting to loop through  a number of elements on a bar chart, until I find the “rect” tag name. When I click on the “rect” tag name, the individual bar is selected from the chart, and I am redirect to another page. Please see below for an image of the bar chart I am working with:

For reference, the bar chart  I am working with is the top right-hand side. The test I want to execute is to click on the first bar in the chart; doing so, will redirect me to an appropriate page. In order to do this I have written the following code in Selenium Webdriver using Eclipse (Java)

WebElement deliveredChartDailyFocus = driver.findElement("delivered-chart-daily"));;
List<WebElement> children = deliveredChartDailyFocus.findElements(By.tagName("rect"));

Iterator<WebElement> iter = children.iterator();
while (iter.hasNext()) {

WebElement we =;


Everything appears to work well in that the above code hits the “rect” element and redirects me to the appropriate page. However, when I hit the page I then get an error as the code is still looking for the “rect” value which isn’t on the new page.

You’ll notice that there is a “break” line missing from the above…..this is because, upon debugging the code I found that when iterating through the loop, the click event does not kick in until the 3rd iteration, I’m assuming because the “rect” element is not visible? Therefore, if I put in a “break” statement it exits out of the loop after the first iteration, and therefore I never get to the part where I carry out the “click” event to navigate to the new page.

Essentially, what I’m after is a way of being able to loop as many times as necessary until the appropriate “rect” element can be located. Upon clicking on that, I am redirected to the new page….only at that point do I want the loop to exit, so that the “NoSuchElementException error is not displayed.

If any more details are required please let me know, would really appreciate any guidance on this.
