[Xorm-devel] data change sensitive objects

[<fi...@so...>]

hi,
I'm interested in implementing data change sensitive object, and i'll post a 
class diagram as soon as possible.
Is some one interested in the project?
we can simply use a makeChangeSensitive and makeNotChangeSensitive.
My question are:
Can this object listen for changes inside a transaction? I don't think so 
but it's mho.
Can this object notify for external(operted on the datastore) and 
internal(simply invocation of setXXX method) changes?And if so it must 
notify only on true data changes not on refreshing, so in that case we must 
check new and old values.
and the best one: collection and extent, like query result, how can be 
managed? If they are only used as model for gui display one cannot check for 
real change but if there is change sensitive code....
Does some one know of some jdo implementation, or similar project, that has 
this feature?
I'll be glad of any suggestion u can send.
bye

P.S. Wes can I commit in CVS the changes the I posted to make the 
InterfaceManager preserve jdo instances identity outside transactions?
