I read that that ActionListner should be used for the java.awt.List class in order to interpret double clicks? I have implemented this method and when an item is double clicked the code inside actionPerformed method gets executed twice? here's the code, a single click will not fire the action event here, any ideas on why I am getting two EditView frames?

public void actionPerformed( ActionEvent ae ) {
Object source = ae.getSource();

if ( source == this.day ) {

new EditView( new Connector(), rows.elementAt( this.day.getSelectedIndex() ), "Edit Event" );

} //if

} //actionPerformed
