jComboBox1.removeAllItems(); returns a ArrayIndexOutOfBoundsException: -1

[roybean]

Im using java netBeans.

i had a jComboBox, that is filled with names and then get the data for these names.

I need in some point of the program to remove all itens from jComboBox and refill with new data.

But when i tried to use jComboBox1.removeAllItems();
is return a ArrayIndexOutOfBoundsException: -1

I tried several ways to solve the problem but the exception maintains:
i put this after the initcomponents()
this.jComboBox1.setModel(new DefaultComboBoxModel());

even when i use the this.jComboBox1.setSelectedIndex(-1); to not had any item selected it gives an exception.


For now to solve i remove all the itens manually and for the fist item i am only managed to remove after the new insertion when this item is the last.

my scary solution:

//remove
            for (int ii = (this.jComboBox1.getItemCount() - 1); ii > 0; ii--) {

                System.out.println("indice" + ii);
                //System.out.println(this.jComboBox1.getSelectedIndex());
                System.out.println(this.jComboBox1.getItemAt(ii));
                this.jComboBox1.removeItemAt(ii);
            }

//new Fill
           for (int ii = 0; ii < playerList.size(); ii++) {
                Players sdf = playerList.get(ii);
                this.jComboBox1.insertItemAt(sdf.getPlayerName(), ii);
            }

//remove ancient fist entrance
            jComboBox1.setSelectedIndex(0);
            this.jComboBox1.removeItemAt((this.jComboBox1.getItemCount() - 1));
            jComboBox1.setSelectedIndex(0);

Please HELP
thanks in advance
cheers
