Solution cannot be read

I hope I get the correct forum… When I open the developer I get “Solution cannot be read. Please check for problems in the underlying file representation”. In the log file I found an unexpected exception : “com.servoy.j2db.persistence.RepositoryException: com.servoy.j2db.persistence.RepositoryException: Cannot handle file versions greater than 40”. I didn’t install anything since the last time, when everything worked fine. Anybody knows how to solve this problem?
Thanks in advance.

I’m using Servoy 6.0.6

Did you open and modify that workspace in a 6.1 servoy?
Because version 40 is servoy 6.0 and you seem to have at least 1 solution/project that have a repository version > 40

You can see that in the file rootmetadata.obj of in the root of a workspace\Solution project dir.

there it says fileVersion:40, what does it say at your place? You could make it 40 (but then be sure that you didn’t really use 6.1 features yet)

You’re right, it says 42, I probably accidentally opened the workspace I used for my 6.0.6 solutions with 6.1.
I’m currently try to update all my solutions to the new version but : is there a way to step back so that I can re-open my solution with 6.0.6?

thats what i already mentioned above make it 40, i think that will work as long as you didn’t do a lot of other changes (using the some new properties)

Yes, I changed all the metadata files for my solutions in the workspace, turning back the repository value from 42 to 40.
It worked.
Thank you.
