Hi karel,
Thanks for reply.
I need to downcast to the implemementation class "session_Impl" to
access the data member of the OBV session valuetype. Because when I have
provided the public accesser function in the session_Impl to get the
values of OBV session Data members.
When I iterate over the seq1_session list and get the session
value type pointer then I am not able to downcast to either of the OBV
session or session_Impl. I am not clear what do you mean by moving the
needed implementation to OBV session class. Its just that I have to
access the data members of the OBV session valuetype for that when I try
to downcast to the OBV Session class it also fails. So I am not able to
get access the data member of the valuetype.
Earlier, i had not tested the code thoroughly on the GCC 4.0.1 now I
have done it and found the same behaviour as its on the vs2005.
The code is working fine on the VS2002.
On further debuging I have found that the session_impl value type is
created and members are demarshalled properly on using reinterpret_cast
I get the same pointer of the session_impl back from the session
valuetype which was allocated at the time of create valuebase. but the
data members are missing.
I am debugging further and trying to single out the problematic area if
I find any thing wierd I will definitely ask for your help.
Once again thanks a lot

first of all, why do you need to downcast to implementation class? Isn't
it better to move needed functionality to the public OBV interface?

IIRC you've had those issues with only VC2005, you were able to compile
working code with GCC and VC2002, has anything changed on this? Anyway,
so far it looks like compiler or compiler parameters issue...
Cheers,
Karel
