JList List Selection Listener

Hello all,
I am working on a project for my java class that is GUI based. Its basically a bank application. There are two JLists on the GUI, one holds customers, and the other holds the accounts associated with the customer that is selected in the customer JList. I know I have to have the ListSelectionListener, and I need it on both of the JLists. I have to keep track of the current customer selected, and the current account that is selected. So I do need the listeners for both of these JLists correct? But when I have both of the JLists have listeners, I just got a bunch of dispatch errors and it looks like it selects an account item in some kind of loop and then terminates my program. I am confused. I have written the valueChanged(ListSelectionEvent e) as the following:

 public void valueChanged(ListSelectionEvent e)
   {
      Object selectedData = ((JList)e.getSource()).getSelectedValue();

      if(selectedData != null)
      {
        //Get the number of the customer selected in the list
        StringTokenizer st = new StringTokenizer(selectedData.toString());
        int custNum = Integer.parseInt(st.nextToken());

        //Set the current customer and show their accounts
        currentCustomer = theBank.getCustomer(custNum);

        accountList.setListData(currentCustomer.getTotalAccountInfo());
        accountList.setSelectedIndex(0);

        if(accountList.getModel().getSize() > 0)
        {
          //Get the account number of the account selected in the list
          StringTokenizer st2 = new StringTokenizer(accountList.getSelectedValue().toString());
          int acctNum = Integer.parseInt(st2.nextToken());
          currentAccount = currentCustomer.locateAccount(acctNum);
        }
        else
        {
           currentAccount = null;
        }
      }

      System.out.println(currentCustomer);
      System.out.println(currentAccount);
   }

So my problem is that I need to get the current selected account. The current customer part works fine, but when I added the account list listener, it went crazy. I can send the whole code as well, but I think the problem lies within this code.

Thanks in advance!

If the same listener is used for both lists, you should do something like this:

if (e.getSource() == firstList)
{
   // processing when first list changes
}
else if (e.getSource() == secondList)
{
   // processing when second list changes
}
