Is it supported to have details inside details?
===============================================

Yes, you can have details inside details.

Suppose we have three objects - "Polls", "Questions" and "Answers." "Answers" 
is a detail of "Questions". We will make "Questions" a detail of "Polls".

One way to do this is to add an integer field "poll" to the "Questions" and 
the following code to the "Poll" client module:


.. code-block:: js

  function on_edit_form_created(item) {
      var q = task.questions.copy();
      
      item.edit_form.find('.form-footer').hide();
      
      q.view_options.form_header = false;
      
      q.on_view_form_created = function(quest) {
          quest.paginate = false;
      };
      
      q.on_before_append = function(quest) {
          if (!item.id.value) {
              quest.alert_error('Poll is not specified.');
              quest.abort();
          }
      };
      
      q.on_before_post = function(quest) {
          quest.poll.value = item.id.value;    
      };
      
      q.set_where({poll: item.id.value});
      q.view(item.edit_form.find('.edit-detail'));
  }
  
  function on_field_changed(field, lookup_item) {
      var item = field.owner;
      item.apply();
      item.edit();
  }
  
  
  function on_before_delete(item) {
      var q = task.questions.copy();    
      q.set_where({poll: item.id.value});
      q.open();
      while (!q.eof()) {
          q.delete();
      }
      q.apply();
  }
