title: How to click an option in an auto-suggest input textfield? Selenium WebDriver
body: <p>I am running a test using Selenium WebDriver</p>
  
  <p>I have an issue with an input textfield <em>("Select Source: By Name:")</em>.
  When I enter a String "ABC Premium News (Australia)" in the textfield, an option would show up. Then I need to click (or select) it. I tried ALL methods w/ fireEvent...no use.</p>
  
  <p>The following is the source code:</p>
  
  <pre><code>driver.get("http://www..."); 
  driver.switchTo().frame("mainFrame");
  WebElement sourceTitle = driver.findElement(By.name("sourceTitle"));
  sourceTitle.sendKeys("ABC Premium News (Australia)"); 
  //Now a "combobox-like" option "ABC Premium News (Australia)" shows up...how do I click it?
  
  // I tried fireEvent...it did not help. The following is one of my trials that does not work:
  DefaultSelenium sel = new WebDriverBackedSelenium(driver,"http://www....");
  sel.type("//input[@id='destination']", "ABC Premium News (Australia)");
  sel.fireEvent("//input[@id='destination']", "keydown");
  // In addition to keydown, I tried: onclick, onfocus, onblur...
  </code></pre>
