1.0.3 version failed to render Tree in Shiny

[Dylan Cissou]

Hi there- the 1.0.1 version from CRAN AND from GitHub of jsTree works fine with the example from the repo (pasted below):

library(jsTree)

ui <- shiny::fluidPage(
  shiny::column(width=4,jsTree::jsTreeOutput('tree')),
  shiny::column(width=8,shiny::uiOutput('chosen'))
)

server <- function(input, output,session) {
  network <- shiny::reactiveValues()
  shiny::observeEvent(input$tree_update,{
    current_selection <- input$tree_update$.current_tree
    if(!is.null(current_selection)) 
      network$tree <- jsonlite::fromJSON(current_selection)
  })
  
  shiny::observeEvent(network$tree,{
    output$results <- shiny::renderPrint({
      str.out <- ''
      if(length(network$tree)>0)
        str.out=network$tree
      return(str.out)
    })    
  })
  
  output$chosen <- shiny::renderUI({
    list(shiny::h3('Selected Items'),
         shiny::verbatimTextOutput(outputId = "results"))
  })
  
  output$tree <- jsTree::renderJsTree({
    nested_string <- apply(states,1,paste,collapse='/')
    jsTree(nested_string,browse = FALSE)
  })
}

shinyApp(ui, server)

But it does lack of some further support fore more arguments such as 'core' newly introduced. However the 1.0.3 version installed from GitHub failed to render. The Rstudio show the HTML widget in viewer but not in the we app itself.

The error I have in the shiny app is:

Listening on http://127.0.0.1:5618
Warning: Error in : $ operator is invalid for atomic vectors
