Hi, you might want to try this: 

 

     public PageReference Cancel(){ 
         PageReference pageRef = ApexPages.currentPage();
         pageRef.setRedirect(true);         
         return pageRef;
    }

Hi, you might want to try this: 

 

     public PageReference Cancel(){ 
         PageReference pageRef = ApexPages.currentPage();
         pageRef.setRedirect(true);         
         return pageRef;
    }
