shiny

Hi:
I use the shinydashboard to develop Web application then meet a problem. As follows:

Server:

  output$track_train <- renderREmap(
    remapB(
    center = BJU,
    zoom = 9,
    color = "grassgreen", 
    markLineData   = markLine_data,
    markPointData  = markPointData,
    markLineTheme  = markLine_Control,
    markPointTheme = markPointTheme,
    geoData = gdata
  ))

UI:

body <- dashboardBody(
tabItems(
  tabItem(tabName = "wifi_01_company",
            tabsetPanel(type = "tabs",
              tabPanel("trail",
                       icon = icon("tag"),
                       REmapOutput("track_train")
                            ),
…………

error message:

If I comment "REmapOutput("track_train")" , everything is OK.

If I modify code: dashboardSidebar(disbale=TRUE), Simple to box(REmapOutput("track_train")), everythig is OK.

How can I output "REmap" object in tabItem? Please help me, thankes.

REmap is R package, the source code: https://github.com/Lchiffon/REmap
