I am porting an application, Tansa, from Carbon to Cocoa.

I have traced the AppleEvents in Terminal, and the difference is that
I do not get the second event (aevt/ansr) when running my Cocoa
application. Do I have to do anything in the Cocoa application to
send this AppleEvent back to the other application?

Sounds like there's a bit of confusion here as to how Apple events work. To clarify: aevtansr is the reply event sent by the target application back to yours when you pass the kAEWaitReply/ kAEQueueReply flag to AESend[Message](). It's what you unpack to extract the target application's result or error value, not something that client programs should send themselves.

Anyway, if you're rewriting your existing Carbon-based Apple event code using ObjC+Cocoa, I'd recommend taking a look at objc-appscript which provides a high-level, easy-to-use ObjC wrapper around the Apple Event Manager:

OTOH, if you're reusing your existing Apple event code largely as-is, I'd suggest posting a testable sample section to the AppleScript- implementors list [1] and perhaps folks there can spot what the problem is.

[1] In theory you should ask on AppleScript-users since it's a client- side question, but experienced developers who can best answer C/ObjC- related questions tend to be on AppleScript-implementors so I'd ask there. -- http://appscript.sourceforge.net http://rb-appscript.rubyforge.org
