Combobox options in cascade update #3681

paoloalba · 2023-01-27T21:15:00Z

Description

I built a cascade of two combobox widgets, in which the value of the first updates the options on the second. Selecting the value of the first combobox initially correctly updates the second combobox, but at every change of value in the first one, the shown options of the second are not reset and just add up. The options attribute of the object itself seems to correctly contain just the updated values, and indeed selecting an "old" value from the second combobox seems to lead to some invalid actions (i.e. the value is not recognised with ensure_option=True).

Reproduce

here some minimal code to reproduce the issue:

wdgt_list = []

cb_1 = wdgt.Combobox(options=[str(eee) for eee in range(10)], description="cb1")
wdgt_list.append(cb_1)

cb_2 = wdgt.Combobox(options=[], description="cb2")
wdgt_list.append(cb_2)


def on_1(_):
    cb_2.options = [f"{cb_1.value}+{eee}" for eee in range(10)]
    cb_2.value = ""


cb_1.observe(on_1, names="value")

wdgt.VBox(wdgt_list)

in order to reproduce the issue, just select values from the first combobox.

Expected behavior

the second combobox should show just the updated options, according to the selected value in the first combobox. If Dropdown is used instead, the code seems to work properly.
