The current version of the Beans Binding library doesn't have converters for 
date and time types e.g.

java.util.Date
java.sql.Date
java.sql.Time
java.sql.Timestamp

These types seem too specialized to be handled directly by the binding library. 
The users have different requirements on the format/style of editing. So, it is 
fine to let the user provide his/her own converter. On the other hand it is not 
nice that the generated application (which uses these types) throws 
PropertyResolverExceptions. So, maybe we should provide some basic converters 
directly in the GUI builder (e.g. wrappers for DateFormat.getInstance() etc.)
