Hi
Yeah... well it was connected the right way, but... I am stupid :D
I tend to have such "tests" working without clicking a button - means, my code was in the init method of the object.
In my euphoria of coding I did not even realized, that my application window is not even open...
Changed the init method to awakeFromNib and now it works :)
I had the same problem with Delphi in school two years ago: The interface item was working seamlessly with every other student, even my teacher did not see what I was doing wrong, and eventually I figured it out by myself~
Thanks anyway,
I already forgot how I got this idea now, but the mail helped ;)
Best regards,
Uli
