Are you testing with Firefox?
If so, there is an issue with click() not working with FF and Webdriver2.35. Please see following site for more details:
https://code.google.com/p/selenium/issues/detail?id=6112From the same site, I was able to find a workaround. I added this code to launch Firefox and it worked for me:
public class TestingInFirefox {
WebDriver driver; //declare Webdriver object
FirefoxProfile profile; //declare Firefoxprofile object
//method to open Firefox browser
public void openBrowser() {
profile = new FirefoxProfile();
profile.setEnableNativeEvents(false);
driver = new FirefoxDriver(profile);
}//end method
}//end class
Please note that you will have to import 'import org.openqa.selenium.firefox.FirefoxProfile' to work with the above.
Hope this helps.
