Error when using selectizeInput (Selectize.js) with plug-ins

[Lalas]

Hello...

Following the instructions described in the following post: "using selectize.js plugin options in Shiny", i have the following example which works:

my_app_tmp <- list(

  ui = shinyUI(fluidPage(

    title = 'Selectize examples',

    h3("Selectize examples with drag and drop"),

    tags$head(

      tags$script(src = "http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js")

    ),

    sidebarLayout(

      sidebarPanel(width=3,

                   #dateRangeInput(inputId = 'mydateRange', label = tags$h5('Date Range: (yyyy-mm-dd)'), start = "2013-09-30", end = "2013-10-01"),

                   selectizeInput(inputId='s1', label= tags$h5('Selectize Example'), choices = NULL, multiple = TRUE,

                                  options = list(

                                    placeholder = 'Please select/type something',

                                    onInitialize = I('function() { this.setValue(""); }'),

                                    plugins = list('restore_on_backspace', 'remove_button', 'drag_drop'),

                                    create =  TRUE,

                                    delimiter = ',',

                                    persist = FALSE

                                  ))

      ),  

      mainPanel(width=9, verbatimTextOutput("out")))

  )),

  server = shinyServer(function(input, output, session) { output$out <- renderPrint({input$s1}) })

)

runApp(my_app_tmp)

 

However, when i un-comment the dateRangeInput controller in the ui; i end up with an error in the javascript console (Chrome); stating:

"Uncaught TypeError: Cannot read property 'empty' of undefined" relating to ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js:6

Would someone be able to help me understand why I am encountering this error. More specifically, why when i comment "dateRangeInput", the shiny app works fine, and when i include it, i get an error.

Thank you very much in advance..

session info:

R version 3.0.2 (2013-09-25)

Platform: x86_64-apple-darwin10.8.0 (64-bit)

and i am using shiny 0.9.1.9009

anyone was able to replicate or resolve this problem??

Found the answer in the source code. 

In particular: In the file, jqueryui.R, on line 83-84, it says:

# IMPORTANT NOTE: If you update jqueryui, make sure you DON'T include the datepicker,

# as it collides with our bootstrap datepicker!

The code below doesn't use a custom version of the jQuery UI, and hence the error.
