Hi Rob,

Could you please provide us with some (ideally minimized) code to reproduce the issue?

Thanks in advance, Christian

Hi Christian,

After the hollidaybreak I found the courage to try to port my application to BaseX's version 112. I get the error-dump shown below. Any idea what is going wrong here?

error-dump:
