RowKeySet is Empty for first row

Question

Hi all,
I am trying to get a table's current row(row is selected with mouse click or arrow down/up) in a bean.With my current code, it works except that if the first row is selected, rowKeySet is null. Any ideas why is it so?
Any pointers are appreciated.
Table code
<af:table value="#{bindings.Department.collectionModel}" var="row"
rows="#{bindings.Department.rangeSize}"
emptyText="#{bindings.Department.viewable ? 'No rows yet.' : 'Access Denied.'}"
fetchSize="#{bindings.Department.rangeSize}"
selectedRowKeys="#{bindings.Department.collectionModel.selectedRow}"
selectionListener="#{GetRowBean.selectedRow}"
rowSelection="single" binding="#{GetRowBean.table}">
Bean code(GetRowBean)
public void selectedRow(SelectionEvent SelectionE){
RowKeySet rowKeySet = table.getAddedSet();
if(rowKeySet != null){
if(rowKeySet.isEmpty() == false){
for(Object tableRowKey: rowKeySet){
table.setRowKey(tableRowKey);
FacesCtrlHierNodeBinding rowData =
(FacesCrtlHierNodeBinding)this.table.getRowData();
Row currRow = rowData.getRow();
DepartmentId = (Integer)currRow.getAttribute("DepartmentId");
Thank you for your time.

Hi Frank,
I am using ADF BC. In my current implementation, I believe that I want the selected row instead of the current row.
May be there are better alternatives to implement the code to retrieve the selected row(mouse click or arrow up/bottom)? Why is the rowKeySet empty if the first row is selected?
Any pointers are appreciated.
Thank you for your time.
