Thanks for the question @schoulten and for the reproducible example, which made it very easy to see your issue. Actually, in the shinylive.io example, I can see the type checker is trying to help you with red squiggles under the values provided to choices
and selected
in both ui.input_checkbox_group()
and ui.update_checkbox_group()
. There, an array of strings for both arguments is expected, so the following works as desired:
def server(input, output, session):
@reactive.effect
def _():
choice = input.aaa()
new_choices = [str(x) for x in options[choice]]
ui.update_checkbox_group(
id="bbb",
choices=new_choices,
selected=new_choices,
)
That said, you're right that there's a difference between how this is handled by the input and update functions. In ui.update_checkbox_group()
, selected
must be a string to produce the desired result, whereas ui.input_checkbox_group()
requests string arrays but at least coerces selected
for you. We should look into this.
Oh, now I see, thanks a lot!
I've noticed some unusual behavior in
input_checkbox_group()
:When I define a reactive effect to update the checkbox choices, the choices are updated in the UI as expected, but the new pre-selected choices are not applied.
Everything works fine if I don't include the reactive effect code. Am I missing something?
