Makie - Observables and removing widgets

Specific Domains Visualization

In case anyone else runs into this, it seems to be related to widgets not being disconnected properly, in this case specifically the Textboxes. See for example this comment on GitHub.

I ended up just completely replacing the Figure and redisplaying it, which works fine. In my case, since I was waiting for the window to close in the main script, this required a little additional work to relink the callback, e.g.:

closed = Base.Event()
selection = Observable(...)  # this triggers and controls figure (re)construction

window_open_callback = Ref{Any}(nothing)
on(selection) do selected
    # filter data etc...
    figure = build_figure(data; selection)

    isnothing(window_open_callback[]) || off(window_open_callback[])
    display(figure)
    window_open_callback[] = on(events(figure).window_open) do is_open
        !is_open && notify(closed)
    end
end

notify(selection)
wait(closed)
