NullPointerException on RowClient accessor after closing RowSetIterator

Question

I have a situation where I create 2 RowSets to 2 different View objects instances.
if I close the first RowSet, I get a NullPointerException when I am iterating over the second one .
While the second iteration, iterator.next() returns a valid object, but invoking any of its properties throws a NullPointerException?
If I don't close the first RowSetIterator, it works. But I suppose I should close all the secondary iterators I create.
What Am I missing here?
ViewObject studentView = findViewObject("StudentList");
RowSet studentRowSet = view.createRowSet(null);
try {
while(studentRowSet.hasNext()) {
StudentRowClient student = (studentRowClient) studentRowSet.next();
System.out.println("Student Info : " + student.getName());
} finally {
studentRowSet.closeRowSet(); // COMMENT THIS LINE TO WORK
ViewObject courseView = findViewObject("CourseList");
RowSet courseRowSet = view.createRowSet(null);
try {
while(courseRowSet.hasNext()) {
CourseRowClient student = (CourseRowClient) courseView.next();
System.out.println("Course Info : " + courseView.getName()); // getName() throws NullPointerException
} finally {
courseRowSet.closeRowSet();
}

If you are going to iterate over an existing rowset, you should use the createRowSetIterator() API, rather than createRowSet.
If you use this instead, does your example work?
See this document for the most commonly used ADF Business Components API's and an overview of when you call them, when you override them, and what they do.
