getWindowHandles() throwing an exception

[Matt]

Hi there. Our automation team has been using your product for a few
months now, and we like it so far. I'm running into a problem though
in your FirefoxDriver with Firefox 3.0. I have a method that
compensates for popup windows, via the getWindowHandles() method. It
can interact with the popup just fine, but after the window closes and
we are back on the base window, it throws this error trying to call
driver.getWindowHandles():

org.openqa.selenium.WebDriverException: Expected response to
getAllWindowHandles but actually got: selectElementById
(selectElementById)

The stack trace is:

Caused by: org.openqa.selenium.WebDriverException: Expected response
to getAllWindowHandles but actually got: selectElementById

I was wondering if you had any insight into this, and whether this was
a known issue or not. I'll be happy to provide you any information I
can assist with.

Thanks.

Also, I did a try/catch for it, and then tried to see if I could do a
simple getWindowHandle() and I get the following exception:

Some more info:

More investigation seems to lead to this is happening after a JS
window.close() is called. If the window is manually closed via user
intervention it can interact just fine. One interesting thing is, I
bypassed the buttons onclick() when it would call a window.close(),
and just did a WebDriver.close(), but even doing the webdriver close()
method, the getWindowHandles would still throw an error.

Hope that helps.

Hi,

This sounds like a bug in the underlying webdriver. Could you please
file an issue so that I've got a fighting chance to remember it.

I think that this behaviour is already tickled by one of the Selenium
RC emulation tests. If anyone's interested in looking into this, I'd
be happy to offer advice.

Regards,

Simon
