Hi All,

Due to previous DB errors we decided to let galaxy-dist repopulate the database (MySQL). We purged all tables from the DB and when restarting galaxy it repopulates the DB on the fly while doing all migration steps. A nicely running galaxy as the result.

I encountered a strange error which might be linked to this... or not...

When changing the attribute of a dataset I get the error below; We never had this before so my guess is that the DB is not constructed properly.

We are at tip 7986:12fcd068b12e of the dist release.

Any pointer to fix this? There is currently no user-data or histories anymore so I can experiment... before I open it for running publicly again...

Thanks;

Alex
