> Using a Bean Display Grid with a bean with a null calendar throws a null pointer exception. 
> org.apache.tapestry5.corelib.pages.PropertyDisplayBlocks.getCalendarDate(PropertyDisplayBlocks.java:56)
> Fix is trivial, simple check that the value is not null before calling getTime(). 
> public Date getCalendarDate() 
>     {
>         Calendar calendar = (Calendar) context.getPropertyValue();
>         if (calendar!=null)
>         {
>                 return calendar.getTime();
>         }
>         return null;
>      }
