Body
I have created a bean validator that I apply to my bean setter method. Instead of getting a JSF validation error, I get an exception raised. Is there a way to make this work, or I should go with a traditional JSF validator? <pre><code>//Bean Method public void setGuestPrimaryEmail(@ValidEmail String email){ guest.getEmails().get(0).setValue(email); } //Validator interface @Target({ElementType.FIELD,ElementType.PARAMETER}) @Retention(RetentionPolicy.RUNTIME) @Constraint(validatedBy = EmailValidator.class) public @interface ValidEmail { String message() default "{invalid}"; Class<? extends Payload>[] payload() default {}; Class<?>[] groups() default {}; } //Validator impl public class EmailValidator implements ConstraintValidator<ValidEmail, String> { private Pattern p; @Override public void initialize(ValidEmail constraintAnnotation) { p = java.util.regex.Pattern .compile("[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"); } @Override public boolean isValid(String value, ConstraintValidatorContext context) { if (DothatUtils.isEmpty(value)) { return true; } boolean invalid = !p.matcher(value).matches(); if (invalid) return false; return true; } } </code></pre> Exception: <pre><code>2013-11-30T20:58:41.747+0000|SEVERE: javax.faces.component.UpdateModelException: javax.el.ELException: /index.xhtml @144,86 value="....": javax.validation.ConstraintViolationException: 1 constraint violation(s) occurred during method validation. </code></pre> Note: I am using GF4 with JSF 2.2.4. If I place my custom annotation on the field, it works as expected.

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.
