[protege-discussion] Problem using Forms Tab in Collaborative mode

[Tania Tudorache]

Hi Tomas,

The problem is a little bit more complicated. When a client connects to 
the server, the project data (that contains the forms information), will 
be copied from the server to the client. After that the client forms are 
decoupled from the server forms. I have explained how this works in an 
email thread on this mailing list some times ago and what the problems are.

So, even if a client is changing the form for a class, then once he logs 
out, the changes are lost. It is also not clear, if the changes should 
be propagated to the server or not. If they were, then all the other 
clients, would suddlenly see a different form for the class (which may 
not suit them). On the longer term, we may support different forms for 
different users, but this requires some reimplementation of the current 
client-server code.

On the shorter term, we will add the possibility to shut down only one 
project on the server; then an admin could edit the classes project, and 
restart it on the server. This would mean that clients could go on 
editing and then at some point, they could reload the project from the 
server with the new forms.
