I personally think writeNestedProperty() is a perfectly valid feature
request to be added to Cayenne.  If you are already using OGNL, such
as in a Tapestry application, that is also an option.  Keep in mind
that nulls give OGNL heartburn, though.  I'm not certain what Cayenne
does with them in readNestedProperty().  (EOF's KVC will return a null
if it encounters a null, while OGNL throws an exception -- that
feature complicated some of my Tapestry pages.)

I might have to look at this a bit more later.


PS. If you create a working writeNestedProperty() before we can and
feel like sharing, please do.
