I am trying to add data to a table and then asserting that data is added by collecting table data in a list but every time it throws me a StaleElement exception error, now I guess it is happening because the list is getting refreshed, so I am not sure how do I handle it.
Here is my implementation
private static List<WebElement> listOfJobs =
driver.findElements(By.xpath(("//*[@id='resultTable']//tbody/tr//a")));
public static List<WebElement> getListOfJobs()
{
try
{
return listOfJobs;
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
public static String generateName()
{
String AlphaNumericString = "abcdefghijklmnopqrstuvxyz";
StringBuilder sb = new StringBuilder(9);
for (int i = 0; i < 9; i++)
{
int index = (int)(AlphaNumericString.length() * Math.random());
sb.append(AlphaNumericString.charAt(index));
}
return sb.toString()+"digi";
}
@SuppressWarnings({ "null" })
public static List<String> listOfJobs()
{
List<String> jobs = null;
for(int i=0; i < OrangeHRMAddJobCategories.getListOfJobs().size(); i++)
{
jobs.add(OrangeHRMAddJobCategories.getListOfJobs().get(i).getText());
}
return jobs;
}
OrangeHRMAddJobCategories jobCategories = new OrangeHRMAddJobCategories();
jobCategories.clickJobTab().clickJobCategoires().clickAdd().setJobCategoryName(UsefulFunctionUtils.generateName()).saveJobCategory();
Assertions.assertThat(UsefulFunctionUtils.listOfJobs().contains("digi"));
I feel that the listOfJobs should be reinjected somewhere but not sure where exactly do I put it because refreshing the page did not work.

Answer
org.openqa.selenium.StaleElementReferenceException: stale element reference: element is not attached to the page document
Indicates that a reference to an element is now “stale” — the element no longer appears on the DOM of the page. The reason for this expectation is may be your DOM got updated or refreshed. For an example, after performing an action like click() your DOM may get updated or refreshed. In this time when you are trying to find an element on DOM you will experience this error.
You have to re-find that element in updated or refreshed DOM
try{
jobs.add(OrangeHRMAddJobCategories.getListOfJobs().get(i).getText());
}catch(org.openqa.selenium.StaleElementReferenceException e){
new WebDriverWait(driver, 10).until(ExpectedConditions.visibilityOf(OrangeHRMAddJobCategories.getListOfJobs().get(i)));
jobs.add(OrangeHRMAddJobCategories.getListOfJobs().get(i).getText());
}
