  actions = {'standard' => true} if actions.class == String && actions == 'standard'
  std_actions = {' 2' => 'edit', ' 3' => 'delete'}

  width = @form['result_set']['actions_width'] || 20*actions.size
  [ actions, "<div class=\"actions\" style=\"width: #{width}px;\">" ] 
end

#dc_actions_for_form ⇒ Object

Creates actions div for edit form.

Displaying readonly form turned out to be challenge. For now when readonly parameter has value 2, back link will force readonly form. Value 1 or not set will result in normal link.
