9572: Intention not working

Donald Mclean wrote:

I have an abstract base class with 9 subclasses. I added a new abstract
function and got the intention popup to implement the function in one of
the subclasses. I added the function to ONE subclass.

Now when I put my cursor at the function name in the base class, I
should get an intention fo implement the function in one of the other
subclasses - at least until all of the non-abstract subclasses have
implementations - but the little intention balloon is nowhere to be seen.

Is this a bug or should I submit a feature request?

My mistake. I also changed the base from an interface to an abstract
class at the same time.
