on each object i get the list of elements on my gwt ui that the data that i populate ui with, and i get only on the last object the list of elements in ui, but want to get it for each object object, can you suggest me what am doing wrong? I add all the objects from first and second callbacks into panel at the end, must i do it in another place? (first asynccallback for the object and the second for the element into this objects)

I might be wrong here, but it seems like you've declared first as an instance variable instead of a local variable. Can you declare it within the for loop and try?
