I need help, the diagrams look like if their elements were deleted.

I tried replacing the .notion and the .uml files in the local history but it throws "No local history available for selected resource".

Had this error one time like two month ago but restarted the proyect, now that i advanced i didn't touch any file as i did two month ago, so i wanted to know... I'm lost?
index.php/fa/42845/0/

The model explorer looks like these, it seems that the elements. dependences, etc were deleted.
index.php/fa/42846/0/

It seems that the model explorer only contains referenced elements. Can you check the size of the .uml file?
It's rather unlikely that Eclipse somehow lost the file content, but rather that an exception happened during the last save of the model. Which Eclipse / Papyrus version are using?

The .uml size is 0 bytes, and as you wrote, the exception happened during the last save of the model.

my current Eclipse/Papyrus version is the following

index.php/fa/42859/0/

Hi Vincent,
renaming the existing files by i.e. adding ".backup" as additional
suffix before saving the new model and deleting the backup files after the new models have been successfully written would enable to restore the prior state of the model. In my regard this is preferable over loosing everything.
How much programming effort would that imply?

Hi,
The solution is an interesting functionality. After discussion with colleagues, the solution is more complex when papyrus is used in a collaborative mode with CDO for example.
