WebElement.isDisplayed() issue

[techi...@gmail.com]

Hello All,

in my selenium code i see webelement was populated, but isDisplayed is not becoming true.  What is wrong here?  how can i debug below value ?

in Debug i see this value return from webelemnt

 [[[[FirefoxDriver: firefox on XP (b3a5d7b1-70f1-4a72-aaab-5e214e836442)] -> xpath: /*]] -> xpath: //*[not(descendant::table[@class='fltr_tbl'])]/*[not(ancestor::table[@class='fltr_tbl'])]/descendant::td/span[text()='VAM:']/../following-sibling::td[1]/div/descendant::input[@type='text' or @type='password'][1] | //*[not(descendant::table[@class='fltr_tbl'])]/*[not(ancestor::table[@class='fltr_tbl'])]/descendant::*[text()='VAM:']/following::input[@type='text' or @type='password'][1]

but following returns false.

 

 if( element.isDisplayed() )

{

visibleElement = element;

break;

}

Thanks

Hi,

It might be due to the element taking few secs to appear in the UI. WebDriver is trying to find the element in the UI immediately which is not appearing in the UI immediately.

Can you mention the ImplicitTime that you are using in the code?

Thanks,

Gopa

Hi Techie,

This looks like a synchronization issue as suggested by Gopa. The Webelement is not present instantaneously , when the WebDriver is trying to find the element in UI. 

To overcome this issue you can use explicit wait until the required web element is present as well as visible.

Once the visible becomes available, you can proceed with other actions.

WebDriverWait wait = new WebDriverWait(driver, 30L);

WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("<<Xpath expression>>")));

 

Please try out this solution and let me know if this works for you.

Also please go through this blog for more info on when to use "visibilityOfElementLocated" or "presenceofelementlocated"

I am doing re try as well but still i see the issues.

initially few seconds page holds different elements then it renders to actual page. Selenium stores all elements when first time page loads ?, in this case I feel page was changed after loading hence selenium wasn't able to find references.?  do i have to reinitialize again?

while( count < RETRY_LIMIT )

{

try

{

textbox = getWebElement( id, byType);

if( textbox == null )

{

throw new StaleElementReferenceException( "The element has still not become visible" );

}

break;

}

catch( StaleElementReferenceException  ex )

{

count++;

}

}

Thanks,

Hi..

did you tried with providing the required sleep or wait time until the page is loaded with actual elements and then checking WebElement is displayed or not?

Thank You,

I am doing sleep/wait and also re try. i think in my case it will not work as selenium holds different DOM elements may i need to re initialize the selenium objects?

Sleep / Wait is not good option while doing automation.

I will suggest, find difference between DOM (Before and After Reload) which will help you. Also you can try isDisplayed / isVisible and see responses.

Are you aware which element is rendered last ? Need to find out that.. Once you know, Wait for that element to display/visible.

And then you can do what you want on that page (Maybe you do PageFactory.initElement.)

No ( page had mulitiple tabs, text boxs), How do we find out which element is rendered last?  can you point me to more examples on PageFactory.initElement?
