Function performing refresh action is as given below.

 
@Action
 public void resetAction(){
        resetForm(); // This function takes care of resetting UI Text fields.

        // Basic Query
        StringBuffer query = new StringBuffer("SELECT p FROM StudentsMaster p");
        query1 = entityManager.createQuery(query.toString());
        jXTable1.invalidate();
        list1.removeAll(list1);
        java.util.List<StudentMaster> newStudentMasterList = query1.getResultList();
                for (Object entity : newStudentMasterList ) {
            entityManager.refresh(entity);
        }
        list1.addAll(newStudentMasterList );
        jXTable1.invalidate();
        jXTable1.repaint();
        jXTable1.validate();
    }  
 

Please help me figure out where am I going wrong.
Thanks

Got the solution guys.....
Just made the list used in this component as observable.
Steps:
1: In Net-Beans go to properties of list that you are using for binding the table.
2: Check observable flag.
