There is a difference in loosing focus on Text and CCombo controls. CCombo don't notify their listeners when focus lost. For example I have example with CCombo widget as below:

package org.eclipse.jface.viewers.tests.bug108431;

import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.CCombo;
import org.eclipse.swt.events.FocusEvent;
import org.eclipse.swt.events.FocusListener;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class CComboTest {

    public static void main(String[] args) {
        Display display = new Display();
        Shell shell = new Shell(display);
        shell.setSize(300, 150);
        shell.setLayout(new FillLayout());

        CCombo combo = new CCombo(shell, SWT.READ_ONLY);
        combo.add("row1");
        combo.add("row2");
        combo.add("row3");
        combo.addFocusListener(new FocusListener() {

            public void focusGained(FocusEvent e) {
                System.out.println("Gained");
            }
            public void focusLost(FocusEvent e) {
                System.out.println("Lost");
                
            }});

        shell.open();

        while (!shell.isDisposed())
        {
            if (!display.readAndDispatch())
                display.sleep();
        }
        display.dispose();        
        
    }
}

- make a change in the ccombo(for example by traverse key up or down), but do not give <enter> or mouseclicks
- select main window of another program running (not this Eclipse instance)
- the changed ccombo don't notify his listeners(This control doesn't lose focus)

When you do the same on a Text, the listener are notified when focus lost.
Bug 108431 depend on it because they don't be notify when focus lost.
