Hi Mikhail,

OOo3.1 has already collision detection system, although it is mostly useful in case system file locking is turned off. If the document was changed during the editing the user gets notification that he might remove changes from somebody else.

If the system file locking is on, the mentioned scenario is only possible when the system file locking does not work as expected. That might happen in heterogeneous networks.

Is there any document, reference, issue, ... on that?

With DEV300_m48 locally built on OpenSolaris x86,
I cannot know how to enjoy with it.

 1. Prepare two existing .odt files: (a) and (b).
 2. Start OpenOffice.org DEV300_m48.
 3. Open (a) with the OOo.
 4. Overwrite (a) with (b) using 'cp' UNIX command.
 5. Make modifications on OOo.
 6. Save the document by pressing Ctrl-S.

Nothing seems to happen. Maybe, I am doing somewhat wrongly.

Regards,
Tora

User X could be informed that the disk file has been altered by someone else -(6) and prompted: (a) Overwrite the file with yours (Warning: someone else's changes will be lost)
 (b) Save your document as another file
 (c) Cancel
