Shiny app: downloadHandler does not produce a file

Question

I can\'t figure out what\'s going on - everything seems to work but my app does not generate a file - although it looks like it does. I run it in Windows, on RStudio 0.98.12

Adding to what Colin D said. It can just be that your idNAME is too long.

I just tested on my app that THIS WORKS:

     output$download_mastergroup <- downloadHandler(...)   #server side
     downloadButton('download_mastergroup ', 'Download overview') #ui side

and that THIS DOES NOT WORK:

     output$download_mastergroup_overview <- downloadHandler(...)   #server side
     downloadButton('download_mastergroup_overview ', 'Download overview') #ui side

So, be concise and it will be allright!
