Question

Is all in the title,
I do not understand the problem this time is a bit different, I used the same Object(List) for two different programs and it does not work in the second time, see :

private void jMenuItem23ActionPerformed(java.awt.event.ActionEvent evt) {                                            
init_creer_client();
List  items  = new ArrayList();
items.add("mawren");
items.add("blabla");
items.add("Bonjour");

CL.show(cartes,"creer_client");       
}   

screenshot about the error :

by cons here its work smoothly :

 import java.awt.Dimension;
 import java.awt.HeadlessException;
 import java.util.ArrayList;
 import java.util.List;
 import javax.swing.JFrame;
 import javax.swing.JPanel;
 import javax.swing.JTextField;
 import org.jdesktop.swingx.autocomplete.AutoCompleteDecorator;

 public class Test_swingx extends JFrame {

public Test_swingx(String title) throws HeadlessException {

this.setTitle(title);
JPanel pan=new JPanel();
JTextField jtf=new JTextField();
jtf.setColumns(20);
List items  = new ArrayList();
items.add("hello");
items.add("marwen");
items.add("allooo");
AutoCompleteDecorator.decorate(jtf, items,false);
pan.add(jtf);
this.setContentPane(pan);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
this.setBounds(280, 150, 500, 200);

}


 public static void main(String[] args) {

Test_swingx tsx=new Test_swingx("helloo swingx");

}
}

can anyone explain to me ?

Answer 1

You have a java.awt.List import should be java.util.List
