title: Jmeter Webdriver sendKeys() won't set a value to a text box with a mask
body: <p>I am trying to fill up a form with "JMeter webdriver" (???) using the <code>sendKeys()</code> function.</p>
  
  <p>I am doing fine in each of the other textboxes (finding it by id, and then setting the value using <code>sendKeys()</code>) , but there is a textbox with a JavaScript mask attached to it (it's a zip code so the mask is 99999-9999).</p>
  
  <p>I can verify that the values are being inserted by the <code>sendKeys</code> function but the mask just reset it back to empty.</p>
  
  <p>This does not happen when I try to fill in the textbox using the FireFox Selenium IDE.</p>
  
  <p>Any ideas how to pass this?</p>
