crosstalk-with-dt's Issues

Great DT + Crosstalk solution but blank Rstudio VIEWER Tab...

Hi Travis and Team,

Thanks
for the wonderful blog post:
https://www.gerkelab.com/blog/2021/09/crosstalk-with-dt/

All OK in the blog post code
(all 3 DFs are generated),
until I enter:

# set up a group of SharedData objects
shared_demo <- SharedData$new(data_demo, key = ~id, group = "shared_obj")
shared_trt <- SharedData$new(data_trt, key = ~id, group = "shared_obj")
shared_fup <- SharedData$new(data_fup, key = ~id, group = "shared_obj")

# send the group to the filtering selection box
filter_select(
  id = "id-selector", label = "ID", 
  sharedData = shared_demo, group = ~id
)

Then,
the Rstudio [VIEWER] Tab opens
but it is completely blank.

Nothing is shown...just white space
and... my Rstudio freezes completely.
I need to restart Rstudio again.

BTW:
This similar Crosstalk PKG code:
https://rstudio.github.io/crosstalk/using.html
with an iris example,
displays just fine in my Rstudio [VIEWER] Tab.

Help, Travis!.
I really want to make this great solution work!.
