title: Selenium fails to select element by id
body: <p>Here is the HTML code of the element:</p>
  
  <pre><code>&lt;input maxlength="64" name="pskSecret" class="text" id="pskSecret" value="" size="32" type="text"&gt;
  </code></pre>
  
  <p>And here is my python code, which tries to select it:</p>
  
  <pre><code>self.driver.find_element_by_id("pskSecret").clear()
  self.driver.find_element_by_id("pskSecret").send_keys(data) # data is variable
  </code></pre>
  
  <p>However I got exception, stating that selenium is unable to locate the element. 
  Any ideas what may be causing the problem</p>
  
  <p>Edit: Also the element is inside an iframe, however I'm accessing other elements in it which are working correctly.</p>
