updateselectinput docs on UI input variables with special characters

[nick-youngblut]

For a number of reasons, I want to use UI input variables that include special characters (e.g., Project ID instead of Project_ID). However, it appears that updateselectinput does not work in such cases (e.g., updateSelectInput(session, "plot type", choices = new_choices)). It would be helpful to include such a warning in the updateselectinput docs.

Interesting, thanks! This behavior seems to be specific to Chrome (I'm on v16.0.5845.187), and applies to both selectInput(selectize = T/F). See below for a minimal reprex and notice how Project ID becomes ProjectID and Other Choice becomes Other choice (even though the <option> HTML sent to the client has the proper, user-supplied, values)

library(shiny)

ui <- fluidPage(
  selectInput("x", NULL, choices = c("Foo", "Bar"), selectize = FALSE),
  verbatimTextOutput("out")
)

server <- function(input, output, session) {  
  updateSelectInput(inputId = "x", choices = c("Project ID", "Other Choice"))
  output$out <- renderPrint(input$x)
}

shinyApp(ui, server)

If this issue is about the select inputId being "plot type", then #3852 will probably fix the original issue.

But it sounds like there's a separate issue with the handling of choices.

Oh interesting, the problem I mentioned in #3900 (comment) goes away if I select "Never translate this page" (it's trying to translate to Arabic?!?)

Anyway, it's not clear what Shiny can do to help the situation without any more details, so I'll be closing the issue
