title: Python selenium: wait until element is clickable - not working
body: <p>I will test a web-app. there is a button available in my table to select all entries.
  I've tried:</p>
  
  <pre><code>driver.wait.until(ExpectedCondition.element_to_be_clickable((By.XPATH, "myXpath"))).click()
  </code></pre>
  
  <p>selenium clicks on the button, but nothing happens. (also with send_Keys(Keys.Return)) the application is developed with GXT, I thing that there is much javascript behind the button. Is there is possibility to wait until a eventloader is ready? waiting before a click solves the problem, but not a solution for automated testing.</p>
