Tabulator and dataframe widget error on edit and won't update anymore

[JulienLrx]

Editing a cell in the tabulator widget throw a key error.

python 3.11.8
Panel 1.4.1
Bokeh 3.4.0
jupyter-bokeh 4.0.1

simple code used to reproduce the error (error is thrown upon exiting the cell) :

df = pd.DataFrame({
    "selected": [True, False, True],
    "Titre": ["TED1", "TED2", "TED3"],
    "id": [1, 2, 3],
    "check": [True, False, True]
}, index=[1, 2, 3])

pn.widgets.Tabulator(df).servable()

stack :

`File /opt/conda/lib/python3.11/site-packages/jupyter_bokeh/widgets.py:162, in BokehModel._sync_model(self, _model, content, _buffers)
    160 elif kind == "ColumnsPatched":
    161     model = content["model"]
--> 162     patches = content["data"]
    164     assert isinstance(model, ColumnDataSource)
    165     model.patch(patches, setter=setter)

KeyError: 'data'`

Same problem with the dataframe widget (pn.widgets.DataFrame).
Also the tabulator or the dataframe won't update anymore after a cell has been edited. (both with implicit and explicit linking)

simple exemple :

df = pd.DataFrame({
    "selected": [True, False, True],
    "Score": [3.14, 6.28, 9.42],
    "Titre": ["TED1", "TED2", "TED3"]
}, index=[1, 2, 3])

df2 = pd.DataFrame({
    "selected": [True, False, True],
    "Score": [3.14, 6.28, 9.42],
    "Titre": ["GGG1", "GGG2", "GGG3"]
}, index=[1, 2, 3])


def get_data(select):
    if select == "test1":
        return df
    else:
        return df2

select = pn.widgets.Select(name="base",options=["test1","test2"])
table = pn.widgets.DataFrame(pn.bind(get_data,select))
pn.FlexBox(select,table)
