Well. Ok. I accept it :)

But right now I have another question. As I shown above I managed to
getProperty('trade_name') using predicate in Sale Order Line context.
And right now, I wonder when/where/how shall I apply this value:

 * using TALES:Default python:
here.getProperty('trade_name',here.portal_domains.generateMappedValue
(here).getTradeName()) (in such case I'll have to restrict me from
'None' generateMappedValue)

 * somewhere in object Document/OrderLine.py by overriding accessor
_setTradeName?

Well, I'd like to have same behaviour as price is set.

Thanks,
Luke
