<rich:beanValidator> not working

[sunay]

Hello All,

I am using <rich:beanValidator> , previously everything was working fine, but when i chaned the jar of hibernate-validator, then annotation is also changed in bean, i changed annotation accordingly, but now it is giving me following exception , and not able to apply validation

javax.faces.FacesException: java.lang.IllegalArgumentException: null passed as group name         

Thanks

For more information : i am using richfaces 3.3.1 GA , is there any problem for rich:BeanValildator for this version ? I am stuck up at this point, my intention is to test annotations so i am usign new hibernate-validator-4.0.2.GA.jar , my test case is working fine, i can able to test my test case , but when i am trying to check validation from UI , it is throwing exception

javax.faces.FacesException: java.lang.IllegalArgumentException: null passed as group name

So my assumption is problem is at UI Side , if any one has faced the same problem then pls guide me through this

Thanks

Sunay
