Question

ArrayList<Fix> fixList = new ArrayList<Fix>();
StringTokenizer st = new StringTokenizer(idlist, ",");
int index = 0;
while(st.hasMoreElements()) {
    Long id = Long.parseLong(st.nextElement().toString());          
    fixList.add(index++,fixManager.getFixById(id));
}

Arraylist here is able to take only one element. I debugged it, it takes only single element but count shows two or more elements are there in arraylist.

Answer 1

Are you sure that the fixManager returns objects for each call? If you try to add null, ArrayList does not complains.
