Summary

0001076: Object to CObject - subclasses loosing all instancevariables

Description

when the superclass of a class A changed from Object to CObject all subclasses of A looses their instance variables (thats bad...).

Also tried the other direction - this time all the generated accessing methods stay unmodified with their statements: "<bewareOf:..." and "propertyValueAt:..."
This happens in all subclasses and the class itself.

For the first case I awaited, that all variables change to fields, a notifier could appear when a generated accessingmethod will change an existing method.

(0001378 - 100 - 100 - 100 - 100 - 100 - 100) bernd 04-14-05 16:19	after another analysis, there're not lost, but they didn't move from instancevariables to classfieds

(0001403 - 158 - 158 - 158 - 158 - 158 - 158) andreas 04-22-05 07:31	I just tried copying an Object subclass to a CObject subclass which seemed to work just fine - the iVars were converted to fields. What version are you using?

(0001414 - 217 - 223 - 223 - 223 - 223 - 223) bernd 04-22-05 13:34	I have a class A and some subclasses of it A1, A2, A3. when I change the superclass of A , class A is fine, but it's subclasses are wrong... (Squeak updateLevel 6638, tweak 1.0 last monticello-packages 1-2 weeks ago)

(0001448 - 112 - 112 - 112 - 112 - 112 - 112) andreas 04-29-05 04:54	Now fixed. Also, iVars will remain iVars and no accessors will be generated not to clobber existing code. Enjoy.
