|Summary||0003057: Loading monticello class which used to have CObject superclass fails|
here is the use case:
I had SophieMediaEvent inherit from CObject. SophieTestingMediaEvent inherited from SophieMediaEvent.
The package that SophieTestingMediaEvent was in was not in the normal release. When Michael changed SophieMediaEvent to inherit from Object, SophieTestingMediaEvent was not in his system.
Fast forward a month or two and trying to load the package with SophieTestingMediaEvent failed, see partial log below, because its loading a class that used to inherit from CObject, but no longer does.
The hack fix was this:
* save image
* Change superclass back to CObject (borking up the class)
* Load borked package. old field IVs are deleted
* add in regular IVs back and write normal setter/getters
* check package in
* QUIT DO NOT SAVE IMAGE
* Open Image
* Reload package from MC.
* all fixed
