Warning when eventReactive() is used

[Marc Girondot]

Hi everyone,

I get this warning when I use eventReactive() and I search for a way to not have it. Any solution ? Thanks:

Warning in structure(NULL, class = "try-error", condition = cond) :

  Calling 'structure(NULL, *)' is deprecated, as NULL cannot have attributes.

  Consider 'structure(list(), *)' instead.

Here is the code to produce the warning:

if (interactive()) {

  ui <- fluidPage(

           actionButton("button", "Show 5 data"),

           tableOutput("table")

  )

  server <- function(input, output) {

    df <- eventReactive(input$button, 

      data.frame(A=1:5, B=6:10)

    )

    output$table <- renderTable({

      df()

    })

  }

  shinyApp(ui=ui, server=server)

}

Here is my session information :

The problem is solved with the recent shiny update 1.0.0 !

Thanks to the development team of shiny !
