title: Django Dajax validating model with many-to-many field
body: <p>I am using django and dajax and I am trying to validate an item that has a many-to-many field. I am using the django forms to create the form for this model. When I submit the form with a submit button and have at least 1 to x number of items selected in the selectbox, the model gets validated. When I use dajax, the model will only validate if I have atleast 2 of the items in the select box are selected.</p>
  
  <p>Does anyone know why this would happen?</p>
  
  <p>Model</p>
  
  <pre><code>#Hints
  class Hint(models.Model):
  title = models.TextField(max_length=200)
  body = models.TextField()
  industryType = models.ManyToManyField(IndustryType)
  screen = models.ManyToManyField(Screen)
  
  #Creates form for a hint
  class HintForm(ModelForm):
  
  class Meta:
      model = Hint
      #widgets = {'industryType': CheckboxSelectMultiple, 'screen': CheckboxSelectMultiple }
      industryType = ModelMultipleChoiceField(queryset=IndustryType.objects.all(),
                                                  widget=CheckboxSelectMultiple())
