Passing an object as parameter to a COM+ application (.NET assembly) from ASP (classic)

[Alexander]

Stituation:
-----------------------
1) COM+ application with .NET components (using regasm, interfaces
etc.)
2) ASP (classic) creates an instance of a object using
Server.CreateObject. The instance is of type ClassA (.NET object). This
is a normal class having some properties. Some properties will be set
in ASP
3) ASP (classic) creates an instance of a object using
Server.CreateObject. The instance is of type ClassB (.NET object). Then
a method in ClassB is called with parameter: a instance of the ClassA
(see 2)

Sample ASP code:
-----------------------
Dim classA, classB

Set classA = Server.CreateObject("Company.Product.ClassA")
classA.Property1 = 1;
classA.Property2 = "test";
classA.Property3 = "test2";

Set classB = Server.CreateObject("Company.Product.ClassB")
result = classB.execute(classA) ' PROBLEM HERE!

classA = nothing;
classB = nothing;
Sample .NET code (interface):
-----------------------
int execute(ref object classA);
Problem:
-----------------------
Calling the method in ClassB is going well but the when we are in the
first line of the method and we inspect the incomming ClassA everything
is as default (after casting it to the right type: ClassA). So no
properties are set. With Respone.Write I verified that the properties
where set successfully.

I'm hoping somebody have some ideas to fix the problem. Its becoming a
bit frustrating. :'(
