title: django-ckeditor: uncaught exception using inlines
body: <p>I have two simple models <strong>Question</strong> and <strong>Choice</strong> (one question has multiple choices). I have used inline formset to add Choices along with adding Questions (through modelAdmin functionality).</p>
  
  <pre><code>class Question(models.Model):
      category = models.CharField(max_length=50)
      question_text = RichTextField(max_length=2000, verbose_name="Question Text", blank=True)
  
  class Choice(models.Model):
      question = models.ForeignKey(Question)
      description = RichTextField(max_length=500, verbose_name="Choice Description")
      is_correct = models.BooleanField(default=False)
  </code></pre>
  
  <p>Now the fields of Choice and Question are RichTextField defined in <a href="https://github.com/shaunsephton/django-ckeditor" rel="nofollow">django-ckeditor</a>. The issue is when I click on "Add another choice" I get an <code>uncaught exception: [CKEDITOR.editor] The instance "id_choice_set-__prefix__-description" already exists</code>, which disrupts the ckeditor functionality.</p>
  
  <p>Any ideas/suggestions how to fix this issue? I think some JS tweaks can help but I have a very limited knowledge in JS/Jquery</p>
  
  <p>Thanks</p>
