r - RStudio Shiny: The confliction between an action button and a submit button -


in r shiny app, have action , submit button.

server <- function(input, output) {   x = reactive(data.frame(x=rnorm(10),y=rpois(10,10),z=runif(10)))   y = eventreactive(input$flush, {     x()[,sample(1:3)]   },ignorenull=false)    output$distplot <- rendertable({     y()       }) }  ui <- fluidpage(   actionbutton("flush","flush order"),   submitbutton("update"),   tableoutput("distplot")  )   shinyapp(ui = ui, server = server)

what want: order of variables randomly changing when click action button.

what happens: have click action button first , subsequently click submit button execute.

question: how can desired behavior while keeping submit button.

there many tabs more submit buttons in app. it's desirable add action button without affecting rest of contents.
