What steps will reproduce the problem?
Here is my code:
WebDriver driver =CFWebDriver.INSTANCE.getDriver();
        String currentWindowHandle=driver.getWindowHandle();        
        forwardCaseLink.click();      
        Thread.sleep(3000);      


        Set<String> openWindowsList=driver.getWindowHandles();        
        String popUpWindowHandle=null;
        for(String windowHandle:openWindowsList)
        {
            if (!windowHandle.equals(currentWindowHandle))
                popUpWindowHandle=windowHandle;
        }

       driver.switchTo().window(popUpWindowHandle);
//popUpWindowHandle remains null giving null pointer exception HERE.
       forwardCaseForm_fcCloseButton.click();


What is the expected output? What do you see instead?
Null Pointer Exception

What version of the product are you using? On what operating system?
Window 7,IE7

Please provide any additional information below.

What is forwardCaseForm_fcCloseButton? Where in the code do you initialize it?

Hi,

forwardCaseForm_fcCloseButton is the button on popup screen.I have
initialized it above using annotation.

It seems to be caused by the same bug as #1754

1754 is not related to window handling.Here when i open one pop up[modal window],and
when i try to make popup window active by using driver.switchTo().window(popUpWindowHandle);
to get the handle of popup when i use getWindowHandles() ,it gives only one handle
[set size=1] instead of two.
Is it the exisiting bug?

This is going to sound silly and I haven't tried it on your example for lack of time,
but try this.

There is a bug of sorts with IE in switching windows when modal dialogs are in the
mix ( possibly true for switching at general ), which I will look into solving later,
that can be bypassed by focusing on some window before performing the action that opens
the new window/modal. 

Say something like driver.switchTo().window( driver.getWindowHandle()) or 
driver.switchTo().window( driver.getWindowHandles().iterator().next() )

The first is more fragile because Selenium can reach a situation where the driver doesn't
point to any window, so getWindowHandle will throw an exception, while getWindowHandles
will work. 

I'm still experimenting myself.

NullPointerException means that forwardCaseForm_fcCloseButton is null
If selenium could not switch window, you'd get NoSuchWindowException

I'm not shure the reason is the same as for #1754, it is just a guess.
I'll try to reproduce the issue and write a comment later.

 WebDriver driver =CFWebDriver.INSTANCE.getDriver();//Get driver for IE7
        String currentWindowHandle=driver.getWindowHandle();//get the main window handle.

        forwardCaseLink.click();        //It opens up one new pop up window.
        Thread.sleep(3000);    //Delay by 3 sec
        Set<String> openWindowsList=driver.getWindowHandles();//It should return set
with size=2,while it returns only one.It doesnt return the pop up window handle.

        String popUpWindowHandle=null;//Variable initialized for newly opened window
with null.It remains null even after the condition in for loop below.
        for(String windowHandle:openWindowsList)
        {
            if (!windowHandle.equals(currentWindowHandle))
                popUpWindowHandle=windowHandle;
        }
       driver.switchTo().window(popUpWindowHandle);//popUpWindowHandle is null still
and we get NullPointerException.Control goes out from here.
       forwardCaseForm_fcCloseButton.click();

I have added my comments above.Kindly have a look.
I am getting null pointer here on below line :

driver.switchTo().window(popUpWindowHandle);

which happens due to the fact that getWindowHandles() doesn`t return the handle of
newly created window as popup.The returned set has just one element.

I'm confused by something. You mentioned in your initial report that you're using Windows
7 and IE 7. That's not a valid combination; Windows 7 shipped with IE 8. There are
tests in the Selenium unit tests that successfully switch to popup windows, and are
able to manipulate them, and I've run those tests under IE 7 without error. Without
the set of HTML files you're actually using, it's going to be difficult to reproduce
this issue.
