Hi,

I want to write a method of a remote object that expects another type of
MarshalByRef object as a parameter. When I run it, I get a SecurityException,
but I don't undestand why.

Let's say the AvSession object is registered as a client-activated object.
It has the following method: AvSession.UpdateSupporter(AvSupporter avs),
where AvSupporter is a MarshalByRef class.

On the client-side, I am doing approximately this:

....
AvSession session = new AvSession();
....
AvSupporter sup = AvSession.Profile; // this is a public get property, works
fine
sup.Profile.Name = "test"; // This calls the set property on a field of the
Profile property, works fine too

// Update changes:
session.UpdateSupporter(sup); // This will fail before even arriving to the
server: SecurityException.

Any help would be appreciated. I think something goes wrong in my
conception, but I would like to know what.

Hi Robert,

Here is the whole StackTrace...
Sorry for the awful presentation, it was copy-pasted from a console
application :-)

Hope it will help...
