This is a key problem, in the case of Business Logic, there is much more
likely to be a load of text fields that become primitives on a Bean, while
in a CMS scenario, you would often want to parse incoming form field(s)
from editing content, because you are not dealing primarily with primitives
but XML.

Sorry, you lost me there ....

Let me keep mucking around in the scratchpad ;)
It would be nice to have a set of reusable components that can be strung
together as needed to perform any required form-based operation, but then,
how long can we wait??
Possible generic components ...... ??
A RequestGenerator that uses a descriptor file to build an Instance, which
could then be Streamed down the pipe, validated and converted to a Bean if
needed, would be helpful, but this would mean implementing castor-mapping
in a Transformer.
As I understand it, this is where the current work on the 'Business Logic'
solution stops being useful for a 'CMS' solution, because everything
happens 'behind the scenes' of the pipeline in Actions, because they are
integrating with external 'Business Logic' not WriteableSources.
thoughts?
