Package org.zkoss.zkmax.bind

Class FormBeanValidator

  • All Implemented Interfaces:
    org.zkoss.bind.Validator
    public class FormBeanValidator
extends org.zkoss.bind.validator.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>
