[boost] type_traits for checking derived type

Hi,

some code:

template <typename DerivedT>
class A
{
BOOST_STATIC_ASSERT((boost::is_convertible<A<DerivedT>*, B*>::value));
[...]
};

class B : public A<B>
{
};

I want to check if the template parameter really specifies a derived type.
But the assert is always false.
How can i solve this?

bye
