JTree: view of selected element

Question

I have a tree object with departments and employees. When the user selects a department or an employee I want to show an edit panel what the user can use to update the department or employee data. To do this, I have implemented the TreeListener.valueChanged method, like below:
public void valueChanged(TreeSelectionEvent e)
DefaultMutableTreeNode node = (DefaultMutableTreeNode)jTree1.getLastSelectedPathComponent();
if (node == null) return;
JUTreeNodeBinding tnb = (JUTreeNodeBinding)node.getUserObject();
if (tnb == null) return;
RowSetIterator rsi = tnb.getParentRowSetIterator();
if (rsi == null) return;
ViewObject vo = tnb.getParent().getViewObject();
if ("mypackage1.EmployeeViewImpl".equals(vo.getClass().getName()))
jSplitPane1.add(pEmployee, JSplitPane.RIGHT);
JUIteratorBinding iter = panelBinding.findIterBinding("EmployeeViewIter");
if (iter == null) return;
iter.bindRowSetIterator(rsi, false);
iter.rangeRefreshed(null);
rsi.setCurrentRow(rsi.getRow(tnb.getRowKey()));
else
jSplitPane1.add(pDepartment, JSplitPane.RIGHT);
As you can see I use a very dirty way to check the type of the currently selected element. But what is the proper way to do this?

Hi,
I think I want to do something similar.
When I use JList component I can easy take selected row:
MyViewRowImpl r = (MyViewRowImpl) myList.getSelectedValue();
When I try to get selected row in similar way from JTree:
Object o = jTree1.getLastSelectedPathComponent();
I have got only string representation of this row. Is it possible to get selected row object.
