[[ repeatIn([line for line in o.order_line if (line.is_option)],'line') ]]
I want to loop on all the lines of an order line wich are options lines (i put a boolean to handle that). The problem is when i don't have option lines in my sale order, i have the error : (<type 'exceptions.assertionerror'="">, AssertionError(), <traceback object="" at="" 0x09064508="">)
Any ideas to handle that problem ? Thanks
