Re: Override tapestry5 datefield default format

Hi!


Maybe this helps:

We wrote our own component, modify as you like


public class DateFormatter
{
     @Inject private Messages_messages;

    @Parameter(required =true, defaultPrefix ="prop")private Date_date;
     @Parameter(required =false, defaultPrefix ="literal")private String_format;

     boolean beginRender(final MarkupWriter writer)
     {
         if (null !=_date) {
             try {
                 if (null ==_format) {
                     _format ="yyyy-MM-dd HH:mm:ss";
                 }
                 final SimpleDateFormat sdf =new SimpleDateFormat(_format);
                 writer.writeRaw(sdf.format(_date));
             }catch (final Exception e) {
                 writer.writeRaw(_date.toString());
             }
         }

         // Abort the rest of the render. return false;
     }
}


and use it like this

<t:TOC.DateFormatter date="yourdatefield" 
format="${message:FORMAT.DateTime}"/>
where TOC is our Library Alias, replace accordingly.
And we provide different format setttings via our application message catalog like this

FORMAT.DateOnly =dd.MM.yyyy FORMAT.DateTime =dd.MM.yyyy - HH:mm:ss
