Issue with Code completion using TextFieldWithAutoCompletion

Hi,

  I have a settings page, where i need a text field with code completion. I am using TextFieldWithAutoCompletion to get this done.
  Below is my code.
  public class MyTextEditor extends TextFieldWithAutoCompletion {
      public FastCodeTextEditor() {
      super (ProjectManager.getInstance().getDefaultProject(), new TextFieldWithAutoCompletionListProvider(Arrays.asList("HEHEHEH", "AAAAA", "BBBBB", "Step")) {
            @Nullable
            @Override
            protected Icon getIcon(@NotNull Object o) {
                return null;  //To change body of implemented methods use File | Settings | File Templates.
            }

            @NotNull
            @Override
            protected String getLookupString(@NotNull Object o) {
                return "Lookup";  //To change body of implemented methods use File | Settings | File Templates.
            }

            @Nullable
            @Override
            protected String getTailText(@NotNull Object o) {
                return "Tail";  //To change body of implemented methods use File | Settings | File Templates.
            }

            @Nullable
            @Override
            protected String getTypeText(@NotNull Object o) {
                return "Type";  //To change body of implemented methods use File | Settings | File Templates.
            }

            @Override
            public int compare(Object o, Object o2) {
                return 0;  //To change body of implemented methods use File | Settings | File Templates.
            }
        }, true, "");
 }
}


My dialog code look like this

public class MyDialog extends JDialog {  
       private JPanel contentPane;
    private JButton buttonOK;
    private JButton buttonCancel;
    private JTextField myName;
      private FastCodeTextEditor templateBody;
 ...
 ...
 ...
 ..
 public MyDialog(MyData data, int selectedIndex, boolean isDetailed) {
 ....
 ...
 ..
 $$$setupUI$$$();
        createDialog();
 ...
 ...
 }
 
 /**
     * Method generated by IntelliJ IDEA GUI Designer
     * >>> IMPORTANT!! <<<
     * DO NOT edit this method OR call it in your code!
     *
     * @noinspection ALL
     */
    private void $$$setupUI$$$() {
 ...
 ...
 ..
 ...
 ..
 templateBody = new FastCodeTextEditor();
 ..
 ...
 ..
 }
}

public class MyTableSettingsConfigurable1 implements Configurable {

 on click on a button
 MyDialog dialog = new MyDialog(data, selectedIndex, true);
}

public class MySettingsConfigurable extends SearchableConfigurable.Parent.Abstract {
    private List<Configurable> myPanels=new ArrayList<Configurable>();

    @Override
    protected Configurable[] buildConfigurables() {
        myPanels.add(new MyTableSettingsConfigurable1());
        myPanels.add(new MyTableSettingsConfigurable2());

        return myPanels.toArray(new Configurable[myPanels.size()]);
    }

    @Override
    public String getId() {
        return "";
    }

    @Nls
    @Override
    public String getDisplayName() {
        return "Fastcode";
    }

    @Nullable
    @Override
    public String getHelpTopic() {
        return null;
    }

}

When i run this code, in the editor when i press space i get the below error
