Body
Following is the code that I came up with (after suggestions from Ajinkya and Alex): Customized Annotation: <pre><code>import java.lang.annotation.Documented; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; import javax.validation.Constraint; import javax.validation.Payload; @Target({ElementType.TYPE}) @Retention(RetentionPolicy.RUNTIME) @Documented @Constraint(validatedBy=HomePageEmptyMessageValidator.class) public @interface HomePageEmptyMessage { String message() default ""; Class<?>[] groups() default {}; Class<? extends Payload>[] payload() default {}; } </code></pre> Customized Validator: <pre><code>import javax.validation.ConstraintValidator; import javax.validation.ConstraintValidatorContext; public class HomePageEmptyMessageValidator implements ConstraintValidator<HomePageEmptyMessage, EmergencyMessages> { @Override public void initialize(HomePageEmptyMessage homePageEmptyMessage) { } @Override public boolean isValid(EmergencyMessages emergencyMessages, ConstraintValidatorContext context) { if (emergencyMessages == null) { return false; } Integer messageEnabled = emergencyMessages.getMessagesEnabled(); if (messageEnabled != null) { if (messageEnabled == 1) { String homePageMessage = emergencyMessages.getHomePageMessage(); if (Util.isNullOrEmpty(homePageMessage)) { return false; } else { return true; } } else { return true; } } return false; } } </code></pre> Usage of customized annotation in the code: <pre><code>@Entity @Table(name="emergency_messages") @HomePageEmptyMessage(message="Home page annoucement cannot be empty if the Display Announcement is set to Yes") public class EmergencyMessages implements Serializable { private static final long serialVersionUID = -7870767517772161300L; @Id @GeneratedValue(strategy=GenerationType.IDENTITY) @Column(name="id", nullable=false) private Integer id; @Column(name="home_page_message") private String homePageMessage; @Range(min=0, max=1, message="Please select one of the display announcement value") @Column(name="messages_enabled") private Integer messagesEnabled; } </code></pre> I hope it helps someone.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
