title: Dynamic JSF converter
body: <p>The data access layer behind my JSF app uses two different formats for date fields (sometimes ddmmyyyy, sometimes yyyymmdd); the displayed date is always dd/mm/yyyy.</p>
  
  <p>Is there a way to use two different converters for a single field and decide which one to use dynamically? Like "if this command button is clicked, use this converter, else if this other command button is clicked, use that converter".</p>
