Class BeanValidator

java.lang.Object

org.zkoss.bind.validator.AbstractValidator

org.zkoss.bind.validator.BeanValidator

org.zkoss.zkmax.bind.BeanValidator

All Implemented Interfaces:

org.zkoss.bind.Validator

public class BeanValidator
extends org.zkoss.bind.validator.BeanValidator

A JSR 303 compatible validator for a property-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 a single property of a bean and sets the invalid message by AbstractValidator.addInvalidMessage(ValidationContext, String).

To use this class, you have to add @validator('beanValidator') or @validator('org.zkoss.zkmax.bind.BeanValidator') to the property-binding

Example

 <grid width="600px">
   <textbox id="tb" value="@bind(vm.person.firstName) @validator('beanValidator')"/>
   <label value="@load(vmsgs[tb])"/> 
</grid>
 

It also supports to validate a property of a form which properties are load from a bean, It uses the class of last loaded bean of the form to perform the validation, which means it doesn't support to validate a form that didn't loaded a bean yet.

Example

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