[BUG] Cannot clear active of RadiGroup #11203
Description
Bug Description
Bokeh version 2.3.1
In the documentation, RadioGroup's active state is nullable. However, if I set active to None, the error occurs in the browser and the state remains. This still works in version 2.2.1.
Example Code
# test_radio_group.py
from bokeh.io import curdoc
from bokeh.models import Button, RadioGroup
clear_btn = Button(label='clear')
def clear_active():
radio_btn_group.active = None
clear_btn.on_click(clear_active)
radio_btn_group = RadioGroup(labels=['a', 'b', 'c'], active=1)
curdoc().add_root(radio_btn_group)
curdoc().add_root(clear_btn)
run:
bokeh serve test_radio_group.py
