Hi, I've been reading about the smalltalk exceptions thanks to some suggestions received in this list.
While reading https://gforge.inria.fr/frs/download.php/26600/PBE2-Exceptions-2010-03-02.pdf(page 9) I found the implementation for *Object>>doesNotUnderstand *but there is something I don't understand and I'm wondering if someone can help me. Object»doesNotUnderstand: aMessage "Handle the fact that there was an attempt to send the given message to the receiver but the receiver does not understand this message (typically sent from the machine when a message is sent to the receiver and no method is defined for that selector). " MessageNotUnderstood new message: aMessage; receiver: self; signal. ↑ aMessage sentTo: self. I'm having problem with the line in red. The method is pretty simple, it just create a new MessageNotUnderstood instance and then send the message: and receiver: messages, but it also *signal *the exception, which I was thinking will finish the method execution, but if that's the case, Why the red line? Why returning anything after signaling the exception? Regards, Erlis
