Re: BOOL returned from Objective-C does not getted mapped properly (always true)

Hi, I have updated to the new CamelBones, but I am still having the problem
of NSObject->isEqual not working properly.

To recap the thread below, I am calling -isEqual on cocoa components
(I think NSButtons), and it returns values, which do not work as
booleans in Perl (maybe a memory address).

real code is here:
http://bitbucket.org/thiloplanz/perlpad/src/tip/MyWindowController.pm#cl-229

$sender->isEqual($self->{PerlInputButton}) returns something like "44858369"

This used to work back in the old days...

Any idea on how I can fix or workaround this issue?

Thanks,

Thilo
