title: createDefaultSkin() returned null error in JavaFX custom control
body: <p>Dear Stackoverflow community,</p>
  
  <p>I've implemented a custom control in JavaFX extending <code>Control</code> class.
  Everything is just working fine, but I keep getting the error message </p>
  
  <pre><code>Jan 30, 2015 8:33:31 AM javafx.scene.control.Control impl_processCSS
  SEVERE: The -fx-skin property has not been defined in CSS for 
  CustomView@19e4d42 and createDefaultSkin() returned null.
  </code></pre>
  
  <p>when I run the application.</p>
  
  <p>I read a lot about <code>SkinBase</code> and <code>BehaviorBase</code>, but since everything is working as it is supposed to, I would just like this error to disappear without implementing these classes if possible.</p>
  
  <p>I'm not using CSS and I can't find any method to manually set a default skin.</p>
  
  <p>I would really appreciate your help. Thanks in advance!</p>
