mapboxer_proxy doesn't work with modules

[Camil88]

Hello,
I have encountered an issue with implementing mapboxer_proxy in a modularized app. Simply, after clicking a button I want points to be displayed on a map. Everything works smoothly in a non-modularized app but when I use modules then it doesn't work. Interestingly, leafletProxy works fine even in a modularized app, so I really don't know where the problem lies. Maybe there's some issue with mapboxer_proxy itself? Or maybe I make a mistake somewhere.

Here is a link to StackOverflow where I described my issue + added working app.R code (modularized and non-modularized): https://stackoverflow.com/questions/66509929/why-mapboxer-proxy-is-not-working-in-a-modularized-shiny-app

I also tried with set_data instead of add_circle_layer but it doesn't solve the problem. Could you please advise me on that issue?

@Camil88 It is a problem with the namespace and more or less a bug in mapboxer_proxy.
I need to the change the line shinyId <- session$ns(shiny_id) to shiny_id <- session$ns(shiny_id) (happened when renaming var name).

For now you can solve the issue by providing the namespace in your server function:

# Server #
mod_btn_server <- function(id) {
  moduleServer(id, function(input, output, session)  {
    ns <- NS(id)
    # ...
    observeEvent(input$btn, {
      mapboxer::mapboxer_proxy(ns("map")) %>%
      # ...
    }.
  }
}

I will fix it as soon as possible.
