ListSelectionListener and double clicks

[Kevin Hamrick]

So here is the code below. The problem is that each time I select a cell from the table the 'else' is executing twice. I am not sure how to fix it. Still new and still struggling with swing,
Thanks

pidTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
ListSelectionModel rowSM = pidTable.getSelectionModel();
rowSM.addListSelectionListener(new ListSelectionListener() {
public void valueChanged(ListSelectionEvent le) {

ListSelectionModel lsm = (ListSelectionModel)le.getSource();
if (!lsm.isSelectionEmpty()) {
//no rows are selected

int selectedRow = lsm.getMinSelectionIndex();
//selectedRow is selected
System.out.println("Row num selected =" + selectedRow);
System.out.println("Num =" + pidTable.getValueAt(selectedRow,0));

} else {
 
//int selectedRow = lsm.getMinSelectionIndex();
////selectedRow is selected
//System.out.println("Row num selected =" + selectedRow);
//System.out.println("Num =" + pidTable.getValueAt(selectedRow,0));
}

}
});

correction-the "if" is executing twice...I posted some code where I was trying some different things...my mistake. Either way, if I click the selected cell then I get to executions.

Hi Kevin

See the following code using if(!e.getValueIsAdjusting())
---------------
private void jList1_valueChanged(ListSelectionEvent e)
{
System.out.println("\njList1_valueChanged(ListSelectionEvent e) called.");
if(!e.getValueIsAdjusting())
{
Object o = jList1.getSelectedValue();
System.out.println(">>" + ((o==null)? "null" : o.toString()) + " is selected.");
// TODO: Add any handling code here for the particular object being selected

}
}
