Error: Class not in class table about squeakjs

[codefrau]

With a Spur object memory, classes are supposed to be entered into the global class table. Their identity hash is the index into that class table. The identity hash primitive is supposed to put them there. That index is used instead of a class pointer in object headers.

SqueakJS doesn’t actually use the index or class table at runtime, it just tries to keep track of it. It’s quite possible I never tested that properly.

Workaround from Dan:

First I filed out the class in question (would help if the error told me which it was, but I figured it was the one to which I had added an instvar).

Then I removed the class. Might have to nil its value in Undeclared (I didn’t)

Then I saved and it worked.

Then I filed the class back in from its filout (could add the instvar in the file if desired).

All seems fine.

FWIW, I've implemented this some time ago in TruffleSqueak. 😉
