Hi,

I got this error in program scheduler.
This happened in duplicating (ctrl+click) a reminder event and moving it backward.

Best regards

Thank for reporting this error.
Unfortunately I cannot solve this issue myself, as it happens in the scheduler component I am using. But I have immediately reported the issue to the vendor of the component, in the hope that they can fix the issue. I’ll let you know, when it is fixed.

Can you clearly reproduce the error?
As I tried it here also with a reminder and duplicating it, but was not successful.

I now had various lengthy discussions with the UI vendor. But we all seem to be unable to reproduce the error.
It is still clear, that the error happened on your side.
However, we believe, that it must have been a single circumstance due to ‚whatever’s‘ coincidence.

If you are also unable to reproduce it, I am afraid we currently must leave it like this - in the hope it never happens again.
