  The problem can be described as the code example below.
  
  DataObject dobj =  ¢â‚¬ ¦
  List list = dobj.getList("manyValuedStringProperty");
  list.add(0, null);
  list.add(1, null);
  list.set(1, "Some text"); // ** Will change the value at index
  0 to empty string
  assertNull(list.get(0)); // FAILED
  

Problem conclusion

• This problem occurs when the list was changed, it refreshed
  the list element value then normalized the null value to the
  empty string. This has been corrected.

  Level (Fix Pack) 1.0.1.3 of WebSphere Application Server v7
