I have a form with four columns from a table. When i used a LOV to populate the form, and then save the changes to the form, it doesn't work correctly. It always save the record as the first row. How to fix it. Thanks.

Your problem is that you are not creating another record so the values keeps overriding at first record.

My form has been designed this way: User populates the form using LOV -> Make changes to the record -> Click the 'Save' button in the form to save the changes.

The Pl/SQL for 'Save' button is: Commit;

It looks to me the forms has been updated using rowid, but when i populate the form using LOV, the rowid doesn't change accordingly. The rowid is always equal to 1.

Could you tell me how to fix it. Thanks.

What are you talking about? It is a PSEUDOCOLUMN! You can not INSERT, UPDATE or DELETE value of the rowid pseudocolumn.

I am not updating the rowid. When i click 'Save' button, the oracle form is updating the row using something like: update tablename set col1= , col2= where rowid = . It looks to me: when populating the form using LOV, the form doesn't know the current rowid. It always picks the first rowid and updates the first row.
