🐛 SelectMultiple options setter bug when all values selected

Question

🐛 SelectMultiple options setter bug when all values selected

ollyhensby opened this issue 7 months ago · comments

Description

Setting the options trait of the same SelectMultiple widget when displayed multiple times seems to only set correctly for the first displayed SelectMultiple ONLY when all values are selected. It works as expected otherwise

Just some backstory: I discovered this issue through trying to assign the same SelectMultiple object multiple times to different accordions and noticed this strange behaviour which led me to this issue.

Reproduce

In Jupyterlab, in the first cell, run:

import ipywidgets as w
select_multiple = w.SelectMultiple()
select_multiple.options = ["Test", "Test 2"]
select_multiple.value = ["Test", "Test 2"]
display(select_multiple)
display(select_multiple)

Then in the second cell run:

select_multiple.options = ["Hello"]

We see the error here as only the first display of the object has been set as expected:

Expected behavior

I expect both objects displayed to be the same:

One way I have resolved this for now is to set value to an empty list before setting the options:

select_multiple.value = []
select_multiple.options = ["Hello"]

which then results in the correct output as shown in the above image.
