ChromeDriver click() does not return if currently used frame is killed with same action

[lukeis]

Originally reported on Google Code with ID 2703

What steps will reproduce the problem?
1. Switch to new iframe
2. Click ( iframe close button ) 
3. Continue test ( eg. switch to default frame )

What is the expected output? What do you see instead?
After step 2. test can be continued. Now, the client / server hangs just in click()
and does not return.

Selenium version: 2.8.0
OS: Mac OSX 10.6.8
Browser: Google Chrome
Browser version: 14.0.835.202
ChromeDriver version: 16.0.902.0

Test snippet can be executed against tinymce demo url ( which has these kind of popupplugins
(dynamic iframes) )

{{{
    public void testGoogleChromeKillCurrentFrameByClick( BrowserDriver browserDriver )
throws Exception
    {
        setBrowserDriver( browserDriver );//a set driver eg. Firefox, Chrome 
        driver.get("http://www.tinymce.com/tryit/full.php");//driver is WebDriver

        String identifier = ".mceIcon.mce_emotions";
        waitElement( identifier );
        WebElement tinymcesmileyPopupPluginLink = driver.findElement( By.cssSelector( identifier
) );
        tinymcesmileyPopupPluginLink.click();//tinymce CREATEs a dynamic id iframe as a popup

        //switch to iframe popup
        WebElement tinymcePopupFrame = driver.findElement( By.cssSelector( "iframe[id^=\"mce\"]"
) );
        driver.switchTo().frame( tinymcePopupFrame );

        String coolSmiley = "a>img[src='img/smiley-cool.gif']";
        waitElement( coolSmiley );
        //click a emoticon 
        WebElement tinymcesmileyCoolIcon = driver.findElement( By.cssSelector( coolSmiley
) );
        System.out.println( "before click" );
        tinymcesmileyCoolIcon.click();//adds smiley to tinymce content area, and REMOVEs
the current iframe (popupplugin)
        //Chrome does a click but click does not RETURN.
        System.out.println( "after click" );//FF can pass this, Chrome not, although closing
the browser (which is no use of course indicates that chrome client Driver can come
here although server doesn't)
        driver.switchTo().defaultContent();
    }
}}}

Thanks for the report. I can reproduce the bug with your test. I cannot reproduce the
problem on a simple test page that removes the iframe element when a child link is
clicked. How are you closing the frame?

The problem is that ChromeDriver waits indefinitely because it doesn't receive a load
finished event from the closing frame.

I haven't debugged or run code analysis of tinymce plugin close-up. But I am interested
were you actually able to continue execution on parent page ? And could this have something
to do with the fact when tinymce editor is used, there exists also other iframes in
page ( like the  text edit area for example ) . Could you show your similar example?
Also in case somebody else gets an idea of it.

I think I've run into similar issue.
I test web application that is integrated with paypal.

It works like this:
1. user submits a form (that opens new tab in which user is redirected to web site
page)
2. java servlet validates POST request
3. java servlet sends request to paypal
4. java servlet redirects user to paypal in tab that was opened in step #1

This works fine for Firefox and IE. 
But after clicking on submit button in Chrome, chromedriver doesn't return control
back. 

I can attach chromedriver log, but unfortunately I can't provide any pages (well, it
probably wont help anyway without a servlet).

Encounter with this issue when created test for application using tinyMCE. After some
investigation locate string of js code that produce problem. In tinyMCE it looks like
this:
DOM.setAttrib(id + '_ifr', 'src', 'javascript:""'); // Prevent leak

It is simply set src attribute of iframe to 'javascript:""'. And this action hangs
chromedriver. There is simple example in archive to reproduce this issue. Note: you
can reproduce issue even if you remove code deleting popup from example.

As a work arround for this issue I plan to wrap DOM.setAttrib function inside test
programm an force it do nothing for described case.

Hope my help will be usefull. Please let me know if other solutions exist.

I will comment this issue when try trick with wrapping.

Try solution mentioned above and it works fine. Js code:
    var tempVar = tinymce.DOM.setAttrib;
    tinymce.DOM.setAttrib = function(id, attr, val) {
        if (attr == 'src' && val.trim().match(/javascript\s*:\s*("\s*"|'\s*')/)) {
            return;
        }
        else {
            tempVar.apply(this, arguments);
        }
    }
}())

All you need - simply execute this code in parent frame before calling function closing
current frame.

@DSAstafiev thanks for analysis, and workaround. Awesome. :)

Did you run already it with my tinymce.com example eg. by adding a JavascriptExecutor
this workaround in parent frame? 

I have no env up'n'running for this right now.

We are running into this issue as well. Closing TinyMCE iFrame leaves Chrome driver
hanging indefinitely.  The above Js code did not resolve this issue for me.

I have a similar problem in Firefox:

I have a page where a popup is created through iFrames.

- I use switchTo().frame("LookupWindow") to switch to the popup.
- I then successfully enter some text and look up a value
- Once the value is found, it is displayed as a hyperlink, and I click on on it (still
on the popup)
- The popup now closes (because I clicked on the value in the popup)

This all expected behavior and works fine.  However, the code hangs after the statement
that clicks the value (which in turn closes the window).  It waits forever, does not
report an error at all.

        Mother's medical record number - 2
        Verify Mother's medical record number - 2
    Click on Search button 
    Click on 'If case does not appear above start new case' button
-- The child page is displayed
3. On the Child Page
    Enter the following:
        Date of Birth - Current Date 
        Time of Birth - Current Time

I am running into a similar issue while creating a Document is Microsoft Office 365
Sequence of Steps - 
1. Login to Microsoft Office 365. 
2. Navigate to Team Site
3. Create a Document - (This results in Opening an IFrame)
4. Edit Document & Close Document (This results in closing the iframe)
On using the click() method to close the document, results in closing the iframe.
Now the execute control hangs in click() statement itself.

Closing the issue because it is related to chromedriver1 and is not actual anymore.

If you experience a similar problem with chromedriver2 please raise a new issue on
the chromedriver tracker [1]
