"Wrong parameter" exception connected to ItemRemoved animation

[Bernhard König]

Hi,

sometimes I get the "Wrong parameter" exception below related to the ItemRemoved animation it seems. Unfortunately I have not found a way to reproduce this safely but maybe you got an idea where this issue might come from.

Thanks,
Bernhard

Hello Bernhard,

Thanks for writing.

Indeed, the stack trace gives us useful information about what might cause the issue. Although we can easily address this by performing some additional checks to prevent this exception, it will be great if you manage to narrow down the case to the point where the exception always happens. This will help us understand what exactly causes it because, as you know, checks do fix the case but it is always important to know why it happens.

Thanks for your time.

All the best,

Hi Deyan,

I'll try to find out a way to reproduce it and let you know if I'm able to.

I think it's related to removing a lot (50 to 100) of items from a list at once and leaving this page by pressing the back button right after it. But that is currently just guessing.

Thanks,
Bernhard

Hi Bernhard,

Thank you for the update. We will test how the jump list behaves in the scenario described by you. Let us know if you manage to find anything additional.
