Sorry, Laune, you've right, i bag your pardon as my first post was not so clear. Now i have re-edited it... maybe now the question is clearer. Can you read it again? I don't need to use .size() indeed... my real problem is to access the nested list properties.. In this case i can access the Quantity proterty of OrderLine... but i don't know how to access the measure proverty value in the nested OrderLineMeasure. Thanks a lot
