Don't think the code is easily extractable for you to use, plus it still will have alot of conceptually problems ....
note, there have been talks about serializing a "lightweight persistentcontext with delta's", to allow this kind of remoting - but until now it have just been talks. /max > Hi list, > > Before you stop reading: This is not about the LazyLoadingException :-) > > I am writing framework code to expose simple crud-operations for use in > a generic gui in both 2 and 3-tier environments (richclient).
