Description:
==========
When using Designer to open a project, if we choose to not open it using the "Multi-User System" option,  it throws the following error once  the “Save” button is clicked:

==>
There was an error during save, please try again. If the problem persist, try save as. If that doesn't work, create a new project and try copying your work. If the problem persists, create a new project or contact support.
==>

The error is thrown when you use ClearCase as source control system and the full error console stack is the following:

==>
Exception in DesignerResourceStore.loadResourceFrom() uri:.designtimelibs.keep using unknown file type resource.

Environment:
============
TIBCO Designer 5.x.x
OS: All


Cause:
======
This is due to the project files being in read-only mode in the file-system.

Resolution:
=========
There is no way to disable the error because the files are read only in the file system. If all files are made readable then reopening the project again with the RCS tool, the error will not be seen. It is then possible to use the native RCS tools to rivert unchanged files and commit changes.

Desinger won't allow saving the project and errors are reported.
