title: SendKeys() doesn't work in only one field of my form
body: <p>I have a little problem with the <code>sendKeys()</code>. It doesn't work in only one field in my form. 
  when I fill in the fields, the value of my field is not changed and the test passed without error message.</p>
  
  <p>Ps: I tried to send the value <code>+newVariable.getDecimalPlaces()</code> in another field and it works.
  The problem is only from this field, knowing the <code>XPath</code> is correct because I did click on it.</p>
  
  <p>Anyone to help me, please! Thank you :) </p>
  
  <pre><code>        WebElement decimalPlacesTxtBox = driver.findElement(By.xpath(AreaUtils.XPATH_DECIMAL_PLACES));
          action.doubleClick(decimalPlacesTxtBox).perform();
          decimalPlacesTxtBox.sendKeys("" +newVariable.getDecimalPlaces()); 
  
  **The xpath :** 
      public static final String XPATH_DECIMAL_PLACES     = "//*[@id=\"floatValue\"]";  
  
  </code></pre>
