#11 casting problems with nested classes

[Karl Matthias Hamel]

A runtime error is shown in the following case:

1) filling a vector with nested classes of a binding
class. These nested classes are based on a nested
interface in a collaboration interface.

2) using this vector as parameter for a method in the
corresponding providing class

3) in this method trying to cast an element of the
vector to the type of the nested interface.

In 3 the error is shown:
