WebDriver fails to read a jquery dialog widget

[cces...@gmail.com]

Hello,

I have random error using the chrome driver. I open a dialog using the jquery ui/dialog widget and every now and then I get the following error

OpenQA.Selenium.ElementNotVisibleException : Element must be displayed to click (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 19 milliseconds
Build info: version: '2.26.0', revision: '18041', time: '2012-11-01 19:33:38'
System info: os.name: 'Windows Server 2008 R2', os.arch: 'x86', os.version: '6.1', java.version: '1.7.0_09'
Driver info: driver.version: RemoteWebDriver

The code to select the dialog is 

            var wait = new WebDriverWait(_driver, TimeSpan.FromSeconds(WaitInSeconds));

            wait.Until(ExpectedConditions.ElementIsVisible(By.CssSelector(selector)));

where selector is the  id something  like ("#dialog"). It works but every now and then fails.

any suggestions?

Use an explicit wait to check for the existence of the element before you click on it.  It takes time for the browser to render the element when creating them with jQuery, sometimes Selenium is being quicker than your browser.

Hello Mark,

I am a newbie with selenium I think I am doing explicit wait:

  var wait = new WebDriverWait(_driver, TimeSpan.FromSeconds(WaitInSeconds));

            wait.Until(ExpectedConditions.ElementIsVisible(By.CssSelector(selector)));

is there a better way?

[Mark Collin]

That looks correct, you can also get the element from the wait, so you can do:

WebElement myElement = wait.Until(ExpectedConditions.ElementIsVisible(By.CssSelector(selector)));

So why I get the error that can't find the element? It does not happen all the time but it does every now and then.

Thank you for validating my code.

Hi Mark,

I am using webdriver version 2.26 , do you think the latest may help?

[Mark Collin]

You would need to show all your code so I can get an idea of what is happening. 

 

In isolation the bits you have shown do not explain the error

I found my problem! I was navigating to the page , and search for an element via the wait I showed to you. The page was not fully loaded throwing the error you saw. 

I added a wait for the page title to wait it seems to fix the issue. Now it finds the element I wanted in the 1st place.

Thanks
