Thanks everyone here who helped find edge cases and regressions in Dash 1.11. Dash 1.12 was released this afternoon with fixes for these issues, in addition to a bunch of new features - check it out! 📣 Dash v1.12.0 Release - Pattern-Matching Callbacks Fixes, Shape-drawing, new DataTable conditional formatting options, and more
@mbkupfer I didn’t get a chance to look at your callback_context.inputs_list issue yet but I have not forgotten about it.
@MM-Lehmann Lots of things changed under the hood 
I encourage you to try again with Dash 1.12. If the problem persists start a new topic here - feel free to @ mention me and I’ll take a look but we’ll need a reproducible code snippet in order to help.
