Error while saving the records in the database

Question

Hi,
I am running into a wierd error.
I have built a new page which contains the information about the employees. Some of the fields are updatable fields. The page shows the details of the person who logs into the page.
I am not using EO in this page. The data is queried from the database from VO and displayed in the page and when the records are updated, they are saved in the databased using pl/sql procedure which is
being called from AM. So i am basically not using VO to save the records in the database.
The error which i am getting is,
If 2 users are trying to update the page at the same time, user A's details are updated in user B's page.
This is really causing the issue. Any help is greatly appreciated.
Thanks in advance.

I have posted the code used along with the dialog page. Please review.
