title: JSF render data table content from managed-bean?
body: <p>I'm using Richfaces to develop some web pages, with a datatable I try to display some data information from remote server. But its quite slow to load all data in one time, so I use a cache to store data, Firstly my cache is empty and data table is empty.</p>
  
  <p>The ideal goal is loading one row from server(let say 1mins for each row) and store into my cache, then append into data table's end, my question is how can I render the content of data table from managedbean once I retrieve some new data into cache?</p>
  
  <p>I also use a timer to update the cache values from server during a fixed period (1hour), that means later, new data could be added into cache, and old data could be removed from cache, that all depend on server's latest data. same question when I get a fresh cache and need rerender data table content according to cache values.</p>
  
  <p>Thanks,</p>
