Hi,

In my data model I have:

contractStart extends MappedDate
contractLength extends MappedInt

In some views I would like to show contractEnd which is
contractStart+contractEnd. 

It would be nice if I could reuse all the mapper functionality for
converting to html/json/forms etc, but I can't seem to figure out if
this is possible with the existing code or even by creating a subclass
of MappedField

If add a mapped field with a non-existing column name, I get an
error. If I add a mapped field with the same column name as en existing
field, the original column is not loaded correctly.....

Any hints?
