Re: [Simple-support] Deserialization of type Calendar?

this is really bad news for me. Now I must change all those domain
model classes to use GregorianCalendar. And not only this, but every
single line that sets the Calendar by using

  someObject.setTime(Calendar.getInstance());

must now have a cast to GregorianCalendar :-/

But what is the real reason behind the scenes? Unfortunately, I don't
know much about the internals of the Simple Framework, but isn't it a
possible enhancement to let Simple look at the "class=" attribute and
then delegate to the correct Transformer? Are you going to have that
"fixed" for a future release, or is this behavior inteded and will not
be changed?

I still don't understand the difference why this works with a List
interface (e.g.: List< String > as the member and ArrayList< String >
as the concrete type with "class=java.util.ArrayList" attribute in the
XML code), since "List" is also non-annotated.


Thanks a lot for all the information
