Re: Gnat: broken dispatch tables for interface types ?

[Rod Kay <rodakay@internode.on.net>]

   I seem to have found the cause of my problem.


   In one case, when an Observer registered itself with a Subject, I'd used the ".all'access" notation to convert from a derived Observer 'access' to the base Observer "access" ...

   Self.Keyboard.register_Observer (Self.all'access, ...);



   When I do the conversion explicitly, all is fine ...

   Self.Keyboard.add (lace.event.Observer.view (Self), ...);



   Thank you Vadim, for the tip.



   Also, it seems I managed to introduce a different error in my (not so) cut-down version of the code (ie deriving types within a body, rather than spec), which Dmitri pointed out. Would two bug reports be in order then ?


   Finally, thanks again to all for the prompt, helpful replies.
