Hi,

as NautilusMethodSelected contains also an information about protocol, class, package;
NautilusProtocolSelected contains an information about class and package;
.
.
.

I��ve inherited NautilusClassSelected from NautilusPackageSelected and NautilusProtocolSelected from NautilusClassSelected�� to remove duplication. But as announcement subscription also includes it��s subclasses, if you subscribe to NautilusPackageSelected, you end up receiving also NautilusClassSelected, NautilusProtocolSelected and NautilusMethodSelected.

What is a good way to resolve this (I can simply separate all the classes, but maybe there is something important from conceptual point of view)?

I didn't know announcments are working that way, but it may make sense if you want to group announcments (register once for "WindowAnnouncement" and receiving all kind of
subannouncements (WindowClosed/WindowOpened ��)

I don��t know about performance, but as far as I understand you can also subscribe to ��WindowAnnouncement withAllSubclasses��.

That would be setting yourself up for a heap of duplicates.
