QUESTION
I have a table in which I am saving the bookmark URL. As of now when you click on the button it opens the modal. But as soon as you have the second record and click on that button it doesn't open up the modal. Also when the modal opens as of now it has a href. How can I clean it up and just show the URL?

QUESTION
So I have a use case for a shiny app where the users can enter some value and when clicked on run it would run a model and show the values in the table. Now when I click on bookmark it captures the input values. And when I click on the restore bookmark it does populate the input values. What I want to do is after it restores the input values it should also run the model again and populate the values in the table. In short restore bookmark should populate the values and click on the run button to run the model.How can this be achieved ?
Below is the code for bookmark :
...ANSWER
Answered 2019-Feb-22 at 17:16My first instinct was that you probably need to use onRestore()
as @AndrewTaylor suggested. But after trying to run your code, it was evident that the issue here is fixed by simply fixing the reactivity in the code.
Here is your code, with two small edits: first, the output$x1 was defined twice, so I removed the second one that was not using any reactive values. Secondly, I moved the first output$x1 to be outside of an observeEvent, and made it trigger only when the button is pressed. You should generally not define an output inside an observer, unless it's a special case where it's mandatory, but the way it was done here causes incorrect reactivity. Fixing this is all you needed.
Also, the DT
and dplyr
packages needed to be loaded to make the code fully reproducible.
QUESTION
I have a shiny app with multiple tabs. Each tab has datatables,plotly charts. In one tab I am trying to use the URL bookmark functionality. When I use this bookmarking as a seperate shiny tab, I can click on the bookmarked URL and it would go to the bookmarked state. However in this bigger app when I use the same code the URL is pretty long and doesnt redirect to the bookmarked state. This is how the bookmarked URL looks like
...ANSWER
Answered 2019-Feb-22 at 13:39According to your description I guess for more complex apps you are hitting a browser limit with the encoded state URLs as mentioned in this article:
With an encoded state, the URL could become very long if there are many values. Some browsers have a limit of about 2,000 characters for the length of a URL, so if the bookmark URL is longer than that, it will not work properly in those browsers.
Therefore you should start using saved-to-server bookmarks by setting

I am trying to use the bookmark in R shiny app and the save the bookmarks in a table. First stage I want to save them locally and retrieve them whenever I load this application. Then save them on a database. Here is the code for bookmarking and saving it on the table. The bookmarking as of now works where it does read from the saved RDS.
Also does bookmarking with URL
work on shinyapps.io
which can save the bookmarks to a database residing on AWS.
