I would like to include a button in my shiny app that restarts the shiny session (the purpose being to reset the value of all inputs & action buttons). I am aware that shiny has the session$reset() function, and that the package shinyjs includes the reset() and refresh() functions for this purpose.

These options are working to refresh the page, but when I use them (or when I hit refresh manually), the formatting of my app becomes lost. Here are sample code and images illustrating the problem.

library(rhandsontable)

data = matrix(rnorm(10*10,mean=0,sd=1), 10, 10) 

ui <- fluidPage(
  titlePanel('Patient Search v2.0'),

  sidebarLayout(
    sidebarPanel(
      textInput('search', 'Search')
    ),

    mainPanel(
      rHandsontableOutput('data')
    )
  )
)

server <- function(input, output, session){
  df = data
  output$data <- renderRHandsontable({rhandsontable(df)})

  session$onSessionEnded(stopApp)
}

runApp(list(ui = ui, server = server), launch.browser = TRUE)

Just press `F5` to refresh the page – Pork Chop Apr 10 '17 at 07:17
Same issue when I press `F5`. I'm on a Mac if that helps. – tsouchlarakis Apr 10 '17 at 07:37

Can really help you without some reproducible example – Pork Chop Apr 10 '17 at 07:38

Have a look to [that topic](http://stackoverflow.com/questions/34142841/page-refresh-button-in-r-shiny) – Smich7 Apr 10 '17 at 07:57
@PorkChop The issue occurs in any Shiny app that I run. I don't think it's a problem with Shiny because of that. When I'm running any Shiny app locally, when I refresh the page, it loses the regular format of the shiny app, as shown in my pictures above. This occurs when I hit 'refresh' when I run the app in RStudio as well. Would you have any ideas as to how to prevent this? Thank you very much. – tsouchlarakis Apr 10 '17 at 17:49

I still need you to provide some code – Pork Chop Apr 11 '17 at 13:28

It happens with nearly every shiny app. I just added code to make this reproducible. – tsouchlarakis Apr 11 '17 at 20:00
