[Pharo-users] Programmatic generation of new class

July 29, 2016

      I'm trying to programmatically generate a new class, but am getting the
following error: 

DynamicDescriptorSystem class(Object)>>doesNotUnderstand:
#subclass:instanceVariableNames:classVariableNames:package:

This is the method that I'm trying to execute: 

buildNewDescriptorSystemUsing: aDescriptorSystemClassName

	descriptorSystem := 
	DynamicDescriptorSystem subclass: aDescriptorSystemClassName asSymbol
			instanceVariableNames: ''
			classVariableNames: ''
			package: packageName asString

I see examples of this all over Pharo and I copied this code almost
verbatim. 

What am I doing wrong?
