AddCelebrity.java
public class AddCelebrity {
    @Persist
    private Celebrity celebrity;

    public Celebrity getCelebrity() {
        return celebrity;
    }

    public void setCelebrity(Celebrity celebrity) {
        this.celebrity = celebrity;
    }

}

public class Celebrity {
    private long id;
    private String firstName;
    private String lastName;
    private Date dateOfBirth;
    private Occupation occupation;
    private String biography;
    private boolean birthDateVerified;

    public Celebrity() {
    }

    public Celebrity(String firstName, String lastName,Date dateOfBirth,
            Occupation occupation) {
        this.firstName = firstName;
        this.lastName = lastName;
        this.dateOfBirth = Formats.parseDate("12/02/1981");
        this.occupation = occupation;
    }
....
setter and getter methods
}

I  was using tapestry 5.0.10 everything worked fine, but when I upgraded
application to 5.0.11 I'm getting error:

org.apache.tapestry.internal.services.RenderQueueException Render queue
error in SetupRender[AddCelebrity:celebrity.editor]: Exception instantiating

the interface java.util.Date.
