Panel Tabulator on_click() and on_edit() callbacks not working in Voila #1435

Kalandoros · 2024-01-06T18:21:58Z

First of all thanks for this great project. I'm using voila quite heavily and I like how seamless a notebook can be shown as some kind of application. I hope the project persists for still a long time. Also thanks advance for helping with the issue.

Description

Using the Panel Tabulator to represent tables conveniently, since it offers a lot of customizations, I noticed the following. To get back the clicked row and content of table cells or to get back the changed values when cells are edited for further processing the (on_click() and on edit() are used.
Comparing the behavior of the callbacks between JupyterLab and Voila I noticed, that the callbacks (on_click() and on edit()) are not working in Voila. I might be wrong but due to the reason it works in JupyterLab, I would assume there is something to improve in Voila. For better explanation and demonstration I recorded the gif that shows the different behavior.

Reproduce

To reproduce I created a minimum example as follows:

Cell1

import panel as pn
import pandas as pd
from ipywidgets import *
pn.extension('tabulator', log_level='DEBUG', console_output='replace')

list_event = []

def bad_callback(event):
    print(event)
    list_event.append(event)

debug_view = widgets.Output(layout={'border': '1px solid black'})

@debug_view.capture(clear_output=True)
def get_list(e):
    print(list_event)

tabulator = pn.widgets.Tabulator(pd.DataFrame({'col1': [1, 2], 'col2': [3, 4]}), disabled=False)
tabulator.on_click(bad_callback)
tabulator.on_edit(bad_callback)
tabulator

Cell2

button = widgets.Button(description='click me to get the list of click events', layout={'width': '300px'})
button.on_click(get_list)
button

Cell3

debug_view

Executing the cells in JupyterLab it can be seen, that after clicking random table cells or edit those, the event information of the callsbacks are stored in the list_event and represented by clicking the button click me to get the list of click events
Doing the same in Voila nothing happens and the list list_event stays empty assuming the callback are not working in Voila.

Expected behavior

I would appreciate getting back the clicked row and content of table cells or getting back the changed values when cells are edited for further processing by using the (on_click() and on edit() methods as it does in JupyterLab.

It's just a guess and please prove me wrong but on the browser console I found the following that might be interesting Failed to create module: package: @pyviz/jupyterlab_pyviz; module: ./extension:

Might that be the problem?

There are a couple of reports which are related to this issue.
Since it is workign fine on JupyterLab but not on Voila I guess the root case might be somewhere in voila.
