[TECHNICAL SUPPORT]LPS-34815 DDL - Fix export of numeric and date fields

Hi Eduardo,

as I can see, the modified classes are created by Marcellus, but as I can see you're the leader of the component.

If you take a look at the fix, @NorbertKocsis has removed the serialization part of the values, because it seems, it doesn't make sense at that part, as the value will be a String any time because of the field.getRenderedValue call.

Have we missed something?
