We can add some more validation on the package name in the wizard

the same is for other keywords & reserved words when this is the name of entity ( and it is probable that you hava a
Package or Class entity.. ).

For Class - there are even harder errors, because the code generation gives:

when generating and when opening the facade class, and rest of generation is stopped.

the generated facade class looks like this:

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

package org.bartczak.facade;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.bartczak.model.Class;

/**
 *
 * @author Tomek
 */
@Stateless
public class ClassFacade {
    @PersistenceContext
    private EntityManager em;

    public void create(Class class) {
        em.persist((ERROR));

        class <error> {
        }
    }

    public void edit(Class class) {
        em.merge((ERROR));

        class <error> {
        }
    }

}

This may be treated as another issue, because the editor id throwing NPE for *some* code - and it shouldn't never I assume.
