hi szimszon and massimo,
i have found out what is the problem.
when you append the new virtualfield with
"db.product.virtualfields.append(MyVirtualFields())" you instantiate
it and apply it so for every lazy property, it uses the same
MyVirtualFields class pointing to same object in the memory. i am
sending a patch here however maybe massimo would solve it in a way
more elegant way. for classes with lazy methods you can use
db.product.virtualfields.append(MyVirtualFields) and for every row, it
will instantiate a new MyVirtualFields class.
