Package org.zkoss.bind.validator

Class BeanValidator

  • All Implemented Interfaces:
    Validator
    Direct Known Subclasses:
    BeanValidator
    public class BeanValidator
extends AbstractValidator
    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).

    Since 8.5, you can assign a self-defined message key by appending a key parameter.

    To use this class, you have to add @validator('beanValidator') or @validator('org.zkoss.bind.validator.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>
 
    
 <grid width="600px">
   <textbox value="@bind(vm.person.firstName) @validator('beanValidator', key='fn')"/>
   <label value="@load(vmsgs['fn'])"/>
 </grid>
    Note

    It doesn't supports to validate a property of a form which properties are load from a bean, if you want to validate the form property of the bean, you could use org.zkoss.zkmax.bind.BeanValodator
