List Selection Listener valuechanged fired more than 2 times

I add listselectionlistener when i clicked on a tab

table1 = new ListSelectionListener()
{
  public void valueChanged(ListSelectionEvent e)
  {
    action(e);
  }
};
ListSelectionModel SM = table1A.getSelectionModel();
SM.addListSelectionListener(table1);
SM = table1B.getSelectionModel();
SM.addListSelectionListener(table1);

When i clicked on the row of the table, the action(e) function fired many times. 

private void action(ListSelectionEvent e)
{
  ListSelectionModel lsm = (ListSelectionModel) e.getSource();

  if (lsm.getValueIsAdjusting())
  {
   // nothing
  }
  else
  {
   // my action here
  }
}

The action(e) should fired twice, once is when mouse clicked, once is when mouse release. I had use the getValueIsAdjusting() to counter the mouse click, so my action should be run once. But, my action run many times. i can see this because i need to put a busy dialog inside my action.

You need to set "value is Adjusting" to true.

 SM.setValueIsAdjusting(true);

Please rename SM to sM because a java attribute should be begin with small letter.(Java Convention)
