Summary: InfoLog: possible data loss with granted rights

Initial Comment:
If a user grants another user edit (and/or delete) access 
to the data of his infolog, it might occur that one user 
edits an infolog-entry while the other user deletes exactly 
this infolog-entry meanwhile.

If the first user, who has edited the data, then presses 
the save (or apply) button, NO data is saved (because 
the data-record is missing/deleted). He will neither be 
warned nor will he notice, that no data is saved until he 
tries to find the infolog-entry again, thus thinking, the 
edited data is updated and still present.

A possible solution for this type of situation would be 
some kind of locking-mechanism, where a data-record is 
locked while it is edited by one user, so no other action, 
like edit and/or delete from other users (with granted 
rights) is possible at the same time.

Hi,

locking is no good idea in a "state-less" web application.
Imagine you open an entry to edit it and then click on the
close (X) button of the browser or loose the connection.

What I will implement for the next release is a warning,
that someone else has changed or deleted the entry and the
user can decide then what he wants to do.

Ralf
