wierd template problem

take a look at this code:
C++ Syntax (Toggle Plain Text) 
  1.  
  2. template <class T>
  3. class C {
  4. public:
  5.  
  6. 	class A {
  7.  
  8. 	protected:
  9. 		int x;
  10. 	};
  11.  
  12. 	class B: public A {
  13. 	protected:
  14. 		void write() {
  15. 			cout << x << endl;
  16. 		}
  17. 	};
  18.  
  19. };

when I try to compile with g++ i get:
test.cpp: In member function ‘void C<T>::B::write()’:
test.cpp:18: error: ‘x’ was not declared in this scope

If I remove the template argument of class C all workes fine ( of course )
Does anyone have an ideea of what is going on?

thx in advance

Well where are you exactly using template functionalities in this code segment ??? I don't see its usage anywhere in the code given by you.
I Surf in "C"....

Use this

C++ Syntax (Toggle Plain Text) 
  1. void write() {
  2.    cout << this->x << endl;
  3.  }
Failure is not fatal, but failure to change might be. - John Wooden

It's just a sample I made to hilight the compile error. I might use the template parameter on other methods I didn't post.
