Re: Beginners Digest, Vol 102, Issue 13

Hi Casey,

The target is Browser, which does not override the method.
The hierarchy is: ProtoObject, Object, Model, StringHolder (has the method), CodeHolder, Browser, et seq.

 

I put the halt in StringHolder>>perform:orSendTo: and that didn't bring up the debugger.

 

There are 13 implementers of perform:orSendTo: and I can put a halt in each one in order to start the research, but I don't understand why the hierarchy seems to be bypassed.
