Hi Jeremy,

sorry for the inconveniences - we have indeed a suspicion where you problem might originate. Version 7.8/the latest stable snapshot should contain a fix in this case. Can you reproduce the issue with 7.8?

Cheers,

Lukas

Hi Guys,

Running into some strange exceptions when trying to make changes to data in the database. The function is updating all attributes in a project to include lower case copies. When doing this on specific projects, it consistently fails with the stack trace below. Any thoughts?

Cheers,

Jeremy
