           Summary: Support for Shared Workbooks
           Product: POI
           Version: unspecified
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSSF
        AssignedTo: dev@poi.apache.org
        ReportedBy: vlast3k@gmail.com


Hi,
I've tried to work with a shared XSSF Workbook, and nothing happend. The api
does not recognize that this is a shared WB.
Is this feature missing?
Can it be implemented?
Or is it implemented for a diffrent version of the API?
If it is missing just because it is not implemented - i would like to
contribute it's implementation to the team. 
I just would like somebody with more experience in this API to confirm that
this is technically possible?

Thanks, Vladimir

Vladimir, you are very much welcome to contribute! 

Shared workbooks are not yet supported. XSSF treats shared workbooks just like
any others - it ignores changes made by other users, does not write changes,
etc. 

I'm pretty much sure it is technically feasible to implement. Can you post a
use case? It would help us to better understand what functionality is required
and design the API appropriately. What did you expect to happen 'automatically'
when you were working with a shared XSSF workbook? 

At least three use-cases come to my mind:

 - turn on the "shared mode" on a .xlsx file. This will allow multiple external
users to edit the workbook at the same time. By 'external' I mean Excel 2007
clients.

 - programmatically work with the Revision Table - read changes made by other
users and update the workbook with those changes. A potentially tricky part is
resolving conflicts.

 - track changes made by XSSF and update the Revision History part so that
other users will see / merge them. 

The first one seems trivial, it should be a flag somewhere in workbook.xml. The
other two can take efforts.

Please see http://poi.apache.org/guidelines.html for initial guidelines how to
contribute. 

Regards,
Yegor
