The appraisal pages error out when I apply my VO substitution

Question

Hi All
We are in the process of performing an upgrade from 11i to R12.1.3.
In the 11i instance, Appraisal VO (/oracle/apps/per/selfservice/appraisals/server/AppraisalVO) was substituted to add one more entry in the select clause.
As part of R12, this underlying standard VO has undergone some changes in the select clause. So I have re-done the substitution.
But when I try to apply this substitution, the pages accessing AppraisalVO error out with null pointer exceptions.
The VO is being used in multiple flows. All the flows are throwing NPEs from standard code.
An example of the error from one such flow is as below :
java.lang.Thread.run(Thread.java:619) ## Detail 0 ## java.lang.NullPointerException at oracle.apps.per.selfservice.appraisals.server.AppraisalsAMImpl.isParticipantsReviewDisplayed(AppraisalsAMImpl.java:1642)
The line of code at 1642 is as below:
return new Boolean(!appraisalvorowimpl.getSelfAppraisal().booleanValue());
Any pointers?

Hi Gyan
Yes, as you rightly said, even I could make out that the issue is because getSelfAppraisal() is getting returned as null
But the issue is that when I run the query standalone on Toad, with appraisal ID as parameter, it returns me the row.
However, SelfAppraisal is a transient attribute in the VO and hence am unable to ascertain if the value is getting returned as null or not.
Also, I observed that all the others flows where we are facing NPEs are also originating from the line of code in standard files, where they are trying to access the getters of the RowImpl.
The system is able to get the handle to the RowImpl, however when trying to access the getters in the RowImpl, it errors out.
Any pointers?
