Eclipse WindowBuilder (swing) - some components not accessible in code?

Question

Edit - @Heuster linked another question that answers this.

I just found out about WindowBuilder and I'm making a simple chat client using it to teach myself. Right now I've got the basic chat frame done, but only some of the components that I've added are accessible in the code. Specifically, I can't access my input JTextArea, taInput. Is there something I need to do to be able to reference it (to get the text in it for sending, etc.)?

Here's a picture of the Design view:

And here's a the generated code:

import java.awt.BorderLayout;
import java.awt.EventQueue;

import javax.swing.JMenuBar;
import javax.swing.JMenuItem;

import javax.swing.ScrollPaneConstants;
import javax.swing.border.EmptyBorder;

public class frame extends JFrame

    private JPanel contentPane;
    private JButton btnSend;
    private JTextArea taDisplay;

    /**

    public static void main(String[] args)
    {
        EventQueue.invokeLater(new Runnable()
        {
            public void run()
            {
                try
                {
                    frame frame = new frame();
                    frame.setVisible(true);
                }
                catch (Exception e)
                {
                    e.printStackTrace();

        setContentPane(contentPane);

        JPanel panel = new JPanel();

        });
        btnSend.setBounds(314, 197, 100, 50);
        panel.add(btnSend);

        taDisplay = new JTextArea();
        taDisplay.setLineWrap(true);
        taDisplay.setEditable(false);
        taDisplay.setBounds(10, 11, 404, 180);
        panel.add(taDisplay);

        JScrollPane spInput = new JScrollPane();
        spInput.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
        spInput.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
        spInput.setBounds(10, 197, 294, 49);
        panel.add(spInput);

        JTextArea taInput = new JTextArea();
        taInput.setLineWrap(true);
        spInput.setViewportView(taInput);
    }
}

Answer 1

From the design tab you could right click on the item (taInput) then click rename on the context menu, in the diaog, at the right of the name there where 2 buttons, clic on the (f) button (field) and then ok.
