Element is not displayed error message for the text box which was visible earlier

Question

I am in the process of creating script using WebDriver for filter functionality for an application which has field names , operands and search value text boxes.

I have the script for selecting the values from operands drop down like below

List <WebElement> filterdrp = (List<WebElement>) driver.findElements(By.xpath("html/body/div[6]/div/div[2]/div[2]/div/div[2]/div[1]/div/div[2]/div/div[2]"));
WebDriverWait wait = new WebDriverWait(driver,30);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("/html/body/div[6]/div/div[2]/div[2]/div/div[2]/div[1]/div/div[2]/div/div[2]/div[21]")));
int size = filterdrp.size();
System.out.println(size);
for(int i=1;i<=size;i++)
        {
            Actions actions = new Actions(driver);
            actions.sendKeys(Keys.DOWN).build().perform();//press down arrow key
            actions.sendKeys(Keys.ENTER).build().perform();//press enter
        }

When I run the script without the above lines, the script is able to identify the search value text box and it runs. When I use these lines I get the error message as

The above error is displayed when the control goes to identify the text box for search.

I am getting error at the next line which is below.

driver.findElement(By.xpath("(//input[@type='text'])[5]")).clear();     
driver.findElement(By.xpath("(//input[@type='text'])[5]")).sendKeys(values);
driver.findElement(By.className("ApplyFilter")).click();

I tried webdriver wait and other couple of options but it still throws the error.Please help. I have tried using id, name, css to find the element, It works only with xpath. Couldn't generate Relative xpath as it looks like it doesn't have one.

Answer 1

Not clear actually where you are getting error. Still based on my understanding logically code you have written is fine. It should not through error. Can you try below solutions:

1. You are using "Absolute xpath" for finding element. Please cross check those as they are correct and proper for element you wanted to interact

2. Can you use "Relative xpath". Just a try if it works

3. I have faced few difficulties while using xpath using selenium. Can you try to find element by id or name or css or class with index

4. May be you can find any of the parent class of element first and then check under that class or nesting might help to find child element

5. Best solution would be check the visibility of an element before taking an action
