[protege-discussion] pprj file is never updated in multi-user db-backed projects

I have added a bug report for the saving of the projects in file mode on 
the server. It seems that currently the projects are not saved, even if 
you set the save interval in the server start script:

It was a design decision not to allow form configuration on the client 
side for performance reasons. This means that if you want to change the 
form layout of a class, you should edit the project locally on the 
server and all clients will get then the new layout when they next login 

Even if you change the display slot in a client, this will not be saved 
in the server pprj file.

However, I could not reproduce the bug that you said about loosing the 
forms configurations if you change the name of a class.
