JList problem

[Mika Suomi]

class AsiakasListaHndl implements ListSelectionListener{
public void valueChanged(ListSelectionEvent e) {
JList jlst= new JList(lstCustomers);
String name=(String) jlst.getSelectedValue();
System.out.println(name);}}

This is code in listener and when I click a customer in list it gives the
result twice.First when I click mouse second when I release mouse.Why???

The problem is located in the code you didn't post.

Try calling getValueIsAdjusting() on the event object and avoid doing
your action if it returns true. (In that case it is an event generated
as a part of a sequence of events)
