title: Passing R Shiny reactive SelectInput value to selectizeInput
body: <p>My Shiny app uses open data from a bird atlas, including lat/lon coordinates by species. The bird species names come in different languages, plus as an acronym. </p>
  
  <p>The idea is that the user first selects the language (or acronym). Based on the selection, Shiny renders a selectizeInput list of unique bird species names. Then, when one species is selected, a leaflet map is generated. </p>
  
  <p>I've done a couple of Shiny apps but this time I miss something obvious. When the app starts, all is well. But, the selectizeInput list is not re-rendered when a new language is selected. </p>
  
  <p>All the present code with some sample data is here as a GitHub Gist <a href="https://gist.github.com/tts/924b764e7607db5d0a57" rel="nofollow">https://gist.github.com/tts/924b764e7607db5d0a57</a> </p>
  
  <p>If somebody could point to my problem, I'd be grateful.</p>
