Hi @Russ_Thomas

An EventFiringWebDriver doesn’t implement RemoteWebDriver interface. You’d probably need to cast into EventFiringWebDriver and then get the wrapped RemoteWebDriver.

May I see what is going on with your code that exhibits this problem ?

I’ll look into this to see if it can be done, but seems tough.

Thanks @ThanhTo.

But I’m not doing this as far as I can tell. I’m just running TCs.

I’ll reregister and see if I can dig in closer to the error.

Wow. It **_is_** my code…

```auto
  static void moveBrowser(int x, int y) {
    WebDriver driver = DriverFactory.getWebDriver()
    Capabilities cap = ((RemoteWebDriver) driver).getCapabilities() // BUG HERE
    String browserName = cap.getBrowserName()
    // Because IE is poo
    if(browserName != "internet explorer") {
      driver.manage().window().setPosition(new Point(x, y))
    }
  }

```

What should that say instead?

SOLVED - thanks.

```auto
  static void moveBrowser(int x, int y) {
    WebDriver driver = DriverFactory.getWebDriver()
    Capabilities cap = ((SmartWaitWebDriver) driver).getCapabilities()
    String browserName = cap.getBrowserName()
    // Because IE is poo
    if(browserName != "internet explorer") {
      driver.manage().window().setPosition(new Point(x, y))
    }
  }

```

</div>

How about

```auto
((RemoteWebDriver) (((EventFiringWebDriver) driver).getWrappedDriver())).getCapabilities()

```

First cast the driver returned from `DriverFactory.getWebDriver()` into EventFiringWebDriver. Then retrieve the wrapped WebDriver from `getWrappedDriver()` and finally cast that into `RemoteWebDriver`

Ah @Russ_Thomas

Please note that RemoteWebDriver has method getSessionId(), so if you need that you would need to cast explicitly to RemoteWebDriver. Otherwise casting into SmartWaitWebDriver would suffice
