matrixInputs lose their bookmarked values on restoration

[JohnADawson]

When an application is bookmarked and restored the matrixInputs lose their values.

An example follows.

ui <- function(request) {
  shiny::fluidPage(
    shinyMatrix::matrixInput("my_matrix", "Matrix"),
    shiny::verbatimTextOutput("my_text"),
    shiny::bookmarkButton()
  )
}

server <- function(input, output, session) {
  output$my_text <- shiny::renderPrint(input$my_matrix)
}

shiny::shinyApp(ui, server, enableBookmarking = "url")

Run the app.

Enter "7".

Click "Bookmark...".

Restore the application.

The matrixInput is not seeded with "7", as it ought to be.

Hi @JohnADawson,
thanks for the report. We did not test the bookmarking functionality with the shinyMatrix package yet. I will take a look, why this is not working out of the box

@aneudecker, thank you for shinyMatrix. When do you expect to rectify bookmarking?

[JohnADawson]

The following works.

ui <- function(request) {
  shiny::fluidPage(
    shinyMatrix::matrixInput("my_matrix", "Matrix"),
    shiny::verbatimTextOutput("my_text"),
    shiny::bookmarkButton()
  )
}

server <- function(input, output, session) {
  output$my_text <- shiny::renderPrint(input$my_matrix)
  shiny::onRestore(
    function(state) {
      shinyMatrix::updateMatrixInput(session, "my_matrix", state$input$my_matrix)
    }
  )
}

shiny::shinyApp(ui, server, enableBookmarking = "url")

Hi @JohnADawson,

Bookmarking is currently no use case for us and I cannot give you a timeframe when we will have a proper solution. We are happy about contributions though.

I am glad to see that you found a workaround!
