Code completion for reference methods does not work

For reference methods in the service model, codecompletion does not work.
Also the syntax should be reconsidered, see comment lines.

for OrderDto reference customer add SimpleCustomerDto
// for CustomerDto .orders add OrderDto
// for CustomerDto .orders remove OrderDto

//"remove the translated OrderDto from the orders association of the translated CustomerDto"
//remove OrderDto for CustomerDto.orders

To reproduce (works also in a 2nd Eclipse):

• Open customer-services.sermod
• Type by using codecompeltion: for OrderDto reference
• Now place your cursor after reference en press [ctrl] +[spacebar]
  The codecompletion pop-up shows: "No code completion possible because of earlier errors"
