Use example: extend a ccombo contorller for 'rating' property.
Add a bug in the new controller named org.mycompany.myProject.gencode.custom.RatingCComboController as shown:

package org.mycompany.myproject.gencode.custom;

import org.adichatz.engine.controller.IContainerController;
import org.adichatz.engine.controller.field.CComboController;
import org.adichatz.engine.core.ControllerCore;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.widgets.Display;

public class RatingCComboController extends CComboController {

	public RatingCComboController(String id, IContainerController parentController, ControllerCore genCode) {
		super(id, parentController, genCode);
	}

	@Override
	public void createControl() {
		super.createControl();
		getCCombo().addSelectionListener(new SelectionAdapter() {
			@Override
			public void widgetSelected(SelectionEvent e) {
				setRatingBackGroundColor();
			}
		});
	}

	@Override
	public void setValue(Object value) {
		super.setValue(value);
		setRatingBackGroundColor();
	}

	private void setRatingBackGroundColor() {
		if ("NC-17".equals(getValue()))
			getCCombo().setBackground(Display.getCurrent().getSystemColor(SWT.COLOR_RED));
		else if ("R".equals(getValue()))
			getCCombo().setBackground(Display.getCurrent().getSystemColor(SWT.COLOR_YELLOW));
		else
			getCCombo().setBackground(null);
	}

	@Override
	public void lockEntity(boolean locked) {
		// BUG : this method must be deleted
	}
}
