Hi,
You have to create an interface and your class implement that interface.
And then you have to cast whith that interface.
IA tA = (A)tIter.next();

'>'Hi!
'>' I declare a class-descriptor of A. Its proxy property is set dynamic.
'>'I try to load it from DB by oql command. The return collection is DList(because

set in

How can
'>'I get A from DList except that I must not set A proxy property dynamic?

'>'A class descript:
