Class FormBeanValidator

java.lang.Object

org.zkoss.bind.validator.AbstractValidator

org.zkoss.zkmax.bind.FormBeanValidator

All Implemented Interfaces:

Validator

public class FormBeanValidator
extends AbstractValidator

A JSR 303 compatible validator for a form-binding.

Notice : Before use this validator, you have to configure your environment (depends on the implementation you chosen). Here is a article Integrate ZK with JSR 303: Bean Validation talks about how to set up JSR 303 in ZK with Hibernate implementation.

It validates all the saving properties of a bean and sets the invalid message by AbstractValidator.addInvalidMessage(ValidationContext, String, String).

To use this class, you have to add @validator('formBeanValidator',prefix='p_') or @validator('org.zkoss.zkoss.bind.FormBeanValidator',prefix='p_') to the form-binding, where prefix is an argument of the message name(prefix+property) for a property. Because of the message name is shared between same ValidationMessages, that is same Binder, you have to provide a unique prefix for every FormBeanValidator in same binder.

Example

 <grid width="600px" form="@id('fx') @load(vm.user) @save(vm.user,after='save') @validator('formBeanValidator',prefix='p_')">
   <textbox value="@bind(fx.firstName)"/>
   <label value="@load(vmsgs['p_firstName'])"/> 
</grid>

validate

public void validate(ValidationContext ctx)

sort

protected void sort(java.util.List<javax.validation.ConstraintViolation<?>> viloations)

Sort the violations, make multiple violation order more predictable. By default, sort it by the constraint name.

Parameters:

viloations -

handleConstraintViolation

protected void handleConstraintViolation(ValidationContext ctx,
                                         java.lang.String key,

Handle hibernate ConstraintViolation. By default, it adds to invalid messages.

Parameters:

ctx -

key - the key of message
