IBlogComment has picked up the fields __parent__ and __name__ from
IContained.

Try explicitly specifying the IBlogComment fields in the addform
directive: set_before_add, e.g.

  set_before_add="name email content"


If you add an __init__ constructor to BlogComment then you could use the
fields or keyword_arguments instead, e.g.

  fields="name email content"
