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

Support property level ScriptAssert ----------------------------------- Key: HV-388 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-388 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.
