Enclosing class Problem

Hello

I imported some java code which I need for our project. The import didn't work correctly with an enclosing class. Here the situation :

class A {

protected class B{

}

}

I would like to write

A objectA = new A();

B objectB = objectA.new B();

But MPS does not give me the option to type " new B() " after the " objectA. " .

Anyone knows how i can make an instance within an enclosing class? Changing class B to static is not really an option.

Thx

Jochen
