reactiveValues on shinyApps

[Josh Lindsteadt]

Do reactiveValues behave differently on shinyApps vs on a local machine? I have a part of my app that increases the number of textInputs based on the number of times an actionButton is pressed. That number is a reactiveValue, and it works correctly when ran locally, but the textInputs disappear when it is clicked on my shinyApp.

Thanks!
Josh

Josh,

What is the URL for your application?

Thanks

I did a little more troubleshooting, and think the issues has to do with the reactiveValuesToList(input) function.  On ShinyApps the following code produces the error "Results do not have equal lengths". 

      output$debug <- renderPrint(function(){

          x <- reactiveValuesToList(input)

          x <- ldply(x)

          x

     })

Josh,

Do you mind sharing your application code so we can troubleshoot the problem?

Josh, I think I know what this is. If you add this to your app:

output$debuginfo <- renderPrint({

  str(reactiveValuesToList(input))

})

and a corresponding verbatimTextOutput("debuginfo") in ui.R, I think you'll find that when run on ShinyApps.io there are a couple of "hidden" inputs that are being sent along and included in your input object. So you'll either have to remove these values from x, or construct x explicitly by grabbing the pieces you want from input rather than converting the whole thing.

That was it.  I changed it to explicitly call each input, and now it is working.  Thanks again!
