Unable to resolve stale data error in parent-child page structure.

Question

Hi Experts!
I've got a master-detail page which consists of two VOs(EO based), Lets say
1. MasterTableVO
2. DetailTableVO
This page contains two page buttons "Cancel" and "Apply" till here it works all fine & perfect[by that i mean creating, retrieving, querying etc etc.]
But now i've created another page which is actually a child page of the above mentioned one.
Here the user'll enter to view some default configured financial info or may also update the default settings manually.
In this page, I've got only an advancedTable based on a VO(EO based), lets say
3. PaymentsTableVO
This page has only one page button "Ok" and which returns back to the parent page retaining the AM.
All the three VOs are in the same AM. Functionally untill here also it looks fine, but when i finally apply the data it throws an error on getTransaction().commit();
Error stack:
OAF Error Unable to perform transaction on the record.
Cause: The record contains stale data. The record has been modified by another user.
Action: Cancel the transaction and re-query the record to get the new data.
Plz reply ASAP.
Regards
Ari

Hi Sushant,
Yepp !! I've done this in the AM. After invoking the method from the PGCO.
Here's the code of the PGCO:
