Re: [basex-talk] Array Size Exceptions

17 Dec 2013


      I was unable to replicate the issue with 7.8. Is 7.8 stable enough to be
used in a production environment?
Thanks,
Jeremy

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,
