busyIndicator not showing in R shiny App

Question

I have a shiny app with a tabsetpanel which tabs are also subdivided in 2 tabs, and I wish to show a simple busyIndicator (default loading image) when shiny is busy loading data in one of the subtabs.

simplified code piece:

tabsetPanel(id = "tabs",
    tabPanel(value = 3, ("Tab3"),
           tabsetPanel(id = "subPanel3", position = "left",
                tabPanel(value = 9, ("View"), icon = icon("eye-open", lib = "glyphicon"),
                   busyIndicator(text = "Loading, please wait...", wait = 400), (...)
                   DT::dataTableOutput("lc")

I have used this feature before but this time it is not showing and I don't know why. Has anything been changed? I don't see any needed shinySky update. Thank you!

I have had a similar issue -- though I'm not sure my solution will solve your problem. Also, I'm probably too late to the party, but it might help others.

In my case, the busyIndicator was hidden behind the other output (table, plot, etc.). By moving the busyIndicator line below the dataTableOutput line, it becomes visible. That is, swap the two lines in the tabPanel:

tabsetPanel(id = "tabs",
    tabPanel(value = 3, ("Tab3"),
           tabsetPanel(id = "subPanel3", position = "left",
                tabPanel(value = 9, ("View"), icon = icon("eye-open", lib = "glyphicon"),
                   DT::dataTableOutput("lc")
                   busyIndicator(text = "Loading, please wait...", wait = 400)
