bqplot widgets not triggering observe method when run in voici #121

Any updates or thoughts on this? I ran into a nearly identical error when using toggle buttons to control a matplotlib plot. It works perfectly in a normal ipynb as well as with voila. But, does not work after compiling(?not sure if that's technically correct) to a voici project. Weirdly - every other widget works as expected when attaching observers -- it's only these toggle boxes that seem to be not attaching. Browser console output attached: |

@jtpio looking at the traceback here, could it be related to the coincident error we had? |
It is indeed the same error message as originally reported in jupyterlite/jupyterlite#1424. Although not sure if it's just noise, there is another error coming from |
Executive Summary
bqplot widgets when run in voici don't trigger
observewhen their attributes change so there can be no reaction by external functions to interactions with the bqplot widgets. This only appears to occur when run inside a Voici environment and the same code works properly in JupyterLab and Voila.Description
I have an interactive plot (generated via bqplot) consisting of a
Scatterobject and aLineobject where the idea is you can drag the points in theScatterobject and theLineobject changes to continue connecting those points. The notebook with this plot runs flawlessly in Jupyter lab and voila. However, in voici, I can drag the points in theScatterobject, but theLineconnecting the points does NOT update.Update 7/25/2024: I have now also confirmed that a plot set up with
bq.interacts.HandDrawhave a similar problem, when hand drawing on the graph, the plot changes but no signal is sent via theobservefunction, so no other functions can react to the changes.NOTE: Since this could be a bqplot issue, I have also filed an issue with bqplot, it is issue #1647 in their repo.
Reproduce
I have created a short notebook index.ipynb that illustrates the problem. Since the environment might be crucial, I created a repo containing the notebook as well as the
environment.ymlfile necessary to test it both in voila and voici here.Expected behavior
The expected behavior (seen in both Jupyter lab and Voila) is that dragging points on the Figure shown should result in not only the points moving, but also the line connecting the points getting updated. The line does NOT update when this same notebook is run in Voici. Again, this appears to be because bqplot widgets run inside of Voici do NOT trigger the
observemethod and thus can't call outside functions to respond.Context
