In the following example, the text is not shown in the start. If I click on the "show"-Button the text appears. If I then click on the "hide"-Button nothing else happens anymore.
In fact the "textis$visible" variable has always the correct value, but i think the if-statement in the observeEvent funktion is only calculated after the very first button click.

Is there a way to force observeEvent to re-evaluate the if statement? Or are there other ways to stop shiny from executing code in the server part and restart it again (in the real case there would be a whole bunch of function calls inside the if statement, not just hide and show some text)

```
library(shiny)

ui <- fluidPage(

actionButton(inputId="show","show"),
actionButton(inputId="hide","hide"),

textOutput(outputId = "some_text")
)

server <- function(input, output) {

  textis<-reactiveValues(visible=FALSE)

observeEvent(input$show,
             textis$visible<-TRUE)

observeEvent(input$hide,
             textis$visible<-FALSE)

observeEvent(textis$visible  , if(textis$visible){
  output$some_text<-renderText({"this is some text"})  
})}

shinyApp(ui = ui, server = server)

```
