Ever accidentally set the wrong value in a Readers field and lose the document to the depts of notes security?...
Here's a little trick to make sure you'll never lose another document again.
Firstly create the role in your Db's ACL, 'SuperUser'.
On your form create two fields:
1. ReadersEdit - set as an editable keyword field using the ACL for choices, allow multi-values (or choose appropriate method of populating for yourself).
2. Readers - set as a computed Readers field with the following formula:
"[SuperUser]" : ReadersEdit
Any changes you wish to make to your readers field will have to be made through ReadersEdit. It functions the exact same as a normal readers field, except that anyone with the role 'SuperUser' will always be able to read/ access the documents in your db. Remember, this is a back-door to your security so be selective on who you give the superUser role to!
