I had developed Notes Application on Domino Server 5.0.4a by Notes Designer 6.5.2. I use section control function to limit of person who are able to access some parts of documents. After requester attached document link under control section and submit to approver.This control section will set the authorization of section to a person ,suppose to be Mr.A. Next, another person ,suppose to be Mr.B, opens this document in edit mode ,do nothing then save and exit .Document link was changed to database link with unknown cause. After investigation , I found that document link will be changed to database link when anyone who access this document in edit mode not the same as person who was set the authorization in section control. Document link was not changed if Mr.A access document in edit mode after section 's authorization was changed to Mr.A. Document link was unexpectedly changed to databsae link if Mr.B access document in edit mode after section 's authorization was changed to Mr.A.
This problem found only on Notes 6.5.2 client ( current used version) but we did not face this problem on Notes 5.0.10 client (previous used version) .We also test this application on Domino Server 6.5.2 and got the same problem on Notes 6.5.2 client but not on Notes 5.0.10 and 6.0.1 client.
