I can confirm that v18.1 4D Server can open an uncompiled Project database and users can connect to it and it appears to work. You can get into Design mode and open the structure, methods and forms but you can't make changes to them. You also cannot create new methods or forms. The “+” button in the Explorer is disabled and if you use a keyboard shortcut to create a new method it give you an error “There is no method for this table/form. You can’t create one because the disk is locked.” I’ve checked the v18 documentation and I can’t find an explicit statement about using an uncompiled project database with 4D Server. So I’m not sure if this is something that will be fully implemented in a later version. But it appears that right now an uncompiled Project database is basically in read only mode in terms of the Design environment.
