I see... well, perhaps next time then :)

I'm not sure, but the references Peter and Lief look promising - will go
chase up their responses (thanks guys!)

When you invoke 'Open Call Hierarchy' on a method/constructor, Eclipse
will present you with the places where that method/constructor was
called - so you can easily see where it has been invoked which I find
useful.

In Avalon though, the container runs the constructor and lifecycle of
the component, so opening the call hierarchy of any lifecycle method
always points you to the container utils code, and the call hierarchy of
the constructor always points to no-where (cos' its all done via
reflection).

Essentially I'd like to be able to say - show me all the places where
this component has been "looked up" in client code so you can see where
it's been used - I guess in reality its just an enhanced (or limited,
depending on perspective :) ) search.

Sure, must be possible. We'd still need to generate the meta-data and
put it into the Eclipse environment, but replacing the xconf would be
too difficult I guess (?)

Must need a faster machine then :)

Cheers mate.

PS. Torsten and I just thought of another one, the ability to
graphically view the dependency tree of components that look each other
up.
