Hello, I have problem with getting Manufacturing Order name from Sales Order report. I have code like this:

%for order in objects:
   %for line in order.order_line:
      %for move in line.move_ids:
         ${move.production_id.name}
      %endfor
   %endfor
%endfor

I understand, that I should be able to reach mrp.production.name by this way, but move.production_id return nothing. Anybody can help me find problem?
