I suppose you put "self halt." ?

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.

Hi Dan,
That doesn't sound quite right.
#perform:orSendTo: is probably overridden in Browser, but... have you looked to see if there's an implementation of it on Object or maybe ProtoObject or something like that?
I'm pretty sure that #perform: and cousins are usually general.
Not sure (on a cellphone) without looking at an actual running system, but try looking up the inheritance chain for another implementation of the same selector. That might help.
Let me know either way, when I get back to a real computer I'll look into it for you if you don't get it figured out by then.
Good hunting!
Casey

An inspector for the menu item "accept (s)" reveals a selector of "#perform:orSendTo:" which is implemented in Browser.
I want to follow the code and I put a halt in "#perform:orSendTo:" but the debugger never opened. What gives?
