Java Null pointer exception when trying to click on an element that is present in a block and becomes visible when another element is clicked

Question

I'm trying to click on an element, which is present in a block and the block itself becomes visible, when another element Your Trips is clicked on.

I'm able to find the element and click on Your Trips, but then, when I try to click on the Sign In button in the block I'm getting Null Pointer exception.

I want to automate the sign in process using Page object Model.

• Upkar Singh: you are getting Null Pointer Exception, just because may be in your class you would not able to call the driver instance correctly, i would suggest you to check your program logic correctly.
• Upkar Singh: Also you can paste your code here, so that we can easily check.
• Divya: Thank you for your response. Adding a wait for the element to be visible worked.

Answer 1

You most likely have to wait for the element to be visible. Have a look at https://stackoverflow.com/questions/20903231/how-to-wait-until-an-element-is-present-in-selenium

• Divya: Thank you, adding the wait worked. public void clickOnToBeginLogin() { WebElement element = driver.findElement(SignIn); WebDriverWait wait = new WebDriverWait(driver,10); wait.until(ExpectedConditions.visibilityOf(element)); driver.findElement(SignIn).click(); }
