[hibernate-issues] [Hibernate-JIRA] Commented: (HV-388) Support property level ScriptAssert

[Peter Davis (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HV-388?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=42680#action_42680 ] 

Peter Davis commented on HV-388:
--------------------------------

It would be impossible to support Validator.validateValue(beanType,propertyName,value), no?

Note validateValue is used by UI frameworks like JSF that attempt to validate a form atomically before updating the model.  Granted, JSF basically has no support for class-level validations.  At least the status quo makes a strong distinction between class- and property-level.

>             Project: Hibernate Validator
>          Issue Type: New Feature
>          Components: engine
>    Affects Versions: 4.1.0.Final
>            Reporter: jason shi
>             Fix For: 4.x

> Current hibernate validator's ScriptAssert can only defined on the Class level, not property level.
> In OVal,it can define the ScriptAssert at the property level,eg:
> {code}
> public class BusinessObject 
> {
>   @NotNull
>   public String deliveryAddress;
>   @NotNull public String invoiceAddress;
>   // mailingAddress must either be the delivery address or the invoice address 
>   @Assert(expr = "_value ==_this.deliveryAddress || _value == _this.invoiceAddress", lang = "groovy")
>   public String mailingAddress;
> }
> {code}
> With property level,we can get following benefit:
> 1. Can be used in single property validation, It's very useful in UI layer validation
> 2. The validation rule is close to the property definition, it's easy to manage
> In JSR303 spec, the ValueContext is not passed to the Contrain Validator as a parameter,
> so the validator can't get the "Current Bean" of the current property to be validated.
> The validation engine need to some special work to support this feature.
> OVal can do this, so it won't be a problem for hibernate validator.
