Is your initialize method on the class-side or the instance-side ?
At the very very start of using Squeak this would catch me up.  It
soon became instinctive to notice which side I was working on.

Behavior 

[Ron Teitelbaum] Exactly!  



>  What method should you call to skip initialize? 

basicNew 

[Ron Teitelbaum] Excellent!



More questions:  why isn’t there a command key for debug it? 

[Ron Teitelbaum] No clue.  


 why isn’t my initialize method not running or running without 
setting variables? 

[Ron Teitelbaum] put a halt in your method and run it.  See if the initialize 
is being called at all.  If it is then check the content of your method for 
errors.  If not then your initialize method is spelled wrong, is not on the 
instance side, or there is a new method implemented in your class or a 
superclass that is bypassing the default implementation of #new which is a bad 
thing.  The system gives you a warning to let you know that!! J

All the best,

Ron




Thank you. 

Sincerely, 

Joe.

I just learned this today - we do have a command key (well, command key
sequence) for debug it:

Shift+Cmd+D to "Debug it"
