KeyError 'data' on table edit #5513

Closed nmillerPCMC closed 3 months ago

nmillerPCMC commented 1 year ago

Just trying to get the Tabulator example posted on the main webpage to work. Editing the cells throws a KeyError exception. https://panel.holoviz.org/reference/widgets/Tabulator.html

ALL software version info

panel v1.2.2 ipywidgets v8.1.1 bokeh v3.2.2 jupyter_bokeh v3..0.7 Windows 10 python 3.11 working within VScode v1.82.2 with Jupyter Extension v2023.8.1002501831 (this library, plus any other relevant software, e.g. bokeh, python, notebook, OS, browser, etc)

Description of expected behavior and the observed behavior

should be able to edit without fatal error

Complete, minimal, self-contained example code that reproduces the issue

hoxbro commented 12 months ago

Hi, can you check what versions of Bokeh and ipywidgets_bokeh you have installed?

nmillerPCMC commented 12 months ago

bokeh version 3.2.2

I do not have ipywidgets_bokeh listed as installed. Is it perhaps included within ipywidgets v8.1.0? or do I need to install it directly?

hoxbro commented 12 months ago

Try installing it; be sure you get the latest version 1.5.

nmillerPCMC commented 12 months ago

installed 1.5. Same issue.

hoxbro commented 12 months ago

mmh, I don't have any clear ideas then, it works on my computer.

Can you send me your full package list with pip list or conda env export?

sylvaint commented 10 months ago

Getting same error.

earshinov commented 4 months ago

Same problem. Already tried experimenting with different versions of jupyter-boken, bokeh, ipywidgets, panel etc. Added 

 elif kind == "ColumnsPatched":
+    import sys
+    print(content, file=sys.stderr)
     model = content["model"]
     patches = content["data"]

     assert isinstance(model, ColumnDataSource)
     model.patch(patches, setter=setter)

to jupyter_bokeh/widgets.py directly inside my venv and got this:

{'kind': 'ColumnsPatched', 'attr': 'data', 'model': {'id': '0e79a6be-6a5d-46f3-a5ff-00145578fdab'}, 'patches': {'type': 'map', 'entries': [['name', [[7, 'value UPD']]]]}}

I have no idea where it comes from, but looks like it isn't the format jupyter_boken expects.

I am running this on Windows inside VS Code (with its built-in support for Jupyter notebooks).

maximlt commented 3 months ago

I've been able to reproduce and opened a tentative PR on jupyter_bokeh to fix the reported bug https://github.com/bokeh/jupyter_bokeh/pull/206.
