To delete in Hibernate using 2 Different instance of same class

[mukulrocks]

Hi,

I have a Class name Project and another class Project_PK as per the standard Spring MVC structure.

Project_PK has only Primary which is defined in Project.java and both referring to same Table

When i was saving into the database , I was getting error of non unique object. Same error "Having Non Unique Object Exception" 2 instance of a same class.

Which i resolved it by using merge() rather than save ().

This worked for save but while deleting i am facing same error, can some one help me regarding this ???

Thanks in Advance.

Without some code it's going to be hard to say.
Include the full exception text and stack trace.
