## Shared Prototypes - Exceptions

In some cases, when working online on a shared prototype, Justinmind Prototyper performs synchronization checks with Justinmind servers in order to detect differences between the user’s local copy of a shared prototype and the server’s copy. These checks may detect when a prototype has been deleted from the server, when your permissions to modify a prototype have been revoked or when the prototype has been modified from other computers using the same user.

Some of these checks will throw a message (prototype deleted, or permissions revoked):

However, if the problem is related to locks synchronization, a dialog will be shown with the following options:

If ‘Revert to last revision’ is selected, all your local changes will be lost and the last prototype’s revision will be downloaded from the server again. After all this process you will be able to continue with your work with no problem.

If ‘Work offline’ is selected, the shared workspace will be closed and the current prototype will turn into a non-shared prototype.
