        Set<String> windows = driver.getWindowHandles();
        Iterator<String> iter = windows.iterator();
        System.out.println(driver.getWindowHandles().size());

        // Set Parent windowhandle
        String parent = iter.next();

        // Switch to new window
        driver.switchTo().window(iter.next());
        // get label text in the new window
        System.out.println(driver.findElement(By.xpath("html/body")).getText());
        // close the new window
        driver.close();
        // switch to parent
        driver.switchTo().window(parent);
        // close main window

Hi Hemanth,

This is issue with Modal Dialog: window.showModalDialog()

Looks this issue is not fixed yet, i tried with 2.20 libraries but with no luck.

Would like to add up to this report:
I've a case similar quoted as below:

html:
========
<table>
   <tr>
     <td colspan="1">
          <a href="javascript:ShowProviderPopUp()">
          <img id="ctl00_Image1" src="../../../Images/Plus.png" align="middle" style="border-width:0px;"
/></a>
      </td>
          <td valign="middle">
           <a href="javascript:ShowProviderPopUp()">Register New Provider</a>
           </td>
    </tr>
</table>

<script language="javascript">
    var WinSettings = "center:yes;resizable:no;dialogHeight:550px;dialogWidth:1200px";
    function ShowProviderPopUp() {
        var url = "../../Super/CreateProvider.aspx";
        var retVal = window.showModalDialog(url, null, "status=0;help=0;maximize:no;minimize:no;center:yes;resizable:no;dialogHeight:600px;dialogWidth:900px;titlebar=no,toolbar=no,statusbar=no;");
    }
</script>

Java Source:

driver.findElement(By.id("ctl00_Image1")).click();
Set<String> windows = driver.getWindowHandles();
System.out.println(windows.size());

  for(String handler : windows){
     driver.switchTo().window(handler);
     if (driver.getCurrentUrl().contains("CreateProvider.aspx")){
      System.out.println("Get focus on Create Provider window");  
      break;  
      }  

  }
//Close modal window
 driver.close();
//Switch back to parent
driver.switchTo().window(parentWindowHandle);
//Close parent window 
driver.close();

Observed behavior:
Find some ambiguous results: Some times it runs smoothly, and gives back 2 window handles
and closes the modal and switch back to parent and closes it. ie. Code works :)

While most of the times, it hangs at getWindowHandles() and upon closing the modal
pop up, next lines of code are executed.

Wondering why sometimes the code works?

I learned that javascript executing stops once a modal popup launches and only after
closing focus comes back to parent. but using WebDriver i thought this would not be
an issue

Hi Hemanth, 

I did a small change in code, it works fine. :)

Try the following code:

import java.util.Set;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class AlertClass {
    public static void main(String[] args) throws InterruptedException {
        WebDriver driver = new FirefoxDriver();
        driver.get("file:///D:/html/Index.html");

        String parent = driver.getWindowHandle();

        driver.findElement(By.xpath("html/body/table/tbody/tr/td[2]/a")).click();

        Set<String> availableWindows = driver.getWindowHandles();
        String newWindow = null;
        for (String window : availableWindows) {
            if (!parent.equals(window)) {
                newWindow = window;
            }
        }
        // assertNotNull(newWindow);

        // Switch to new window
        driver.switchTo().window(newWindow);
        // get label text in the new window
        System.out.println(driver.findElement(By.xpath("html/body")).getText());
        // close the new window
        driver.close();
        // switch to parent
        driver.switchTo().window(parent);
        // close main window
        driver.close();
    }
}

Here after clicking on the link, new window gets open, so there are now two windows.

your code:
        Set<String> windows = driver.getWindowHandles();
        Iterator<String> iter = windows.iterator();
        System.out.println(driver.getWindowHandles().size());

        // Set Parent windowhandle
        String parent = iter.next();

        // Switch to new window
        driver.switchTo().window(iter.next());

But how do you assume first item is parent and the next is new window in the set of
windows ?

Hope it helps you :) cheers,,,

Hello kopp.sam@gmail.com,

I just tried to apply your solution, but it still not working for me.

I made my tests with Firefox 11, 10 and 9: I got the same result => the reference of
my dialog box is not find.

FYI: I'm running my tests on Mac OS Lion.

Thank you for your return.

Hi Hemanth and franck.nouama@gmail.com,

Following is my environment:
Selenium version: Working with jar files which I've downloaded in sep 2010, and I am
not sure of the version number.
OS: Windows Xp
Browser: Firefox 3.6.28

Here I am able to run the test and finally it is able to close the browser also.

Suggestion: After clicking on the link, just wait for 1 sec and try.
