It's actually the
MAOneToManyComponent>>value that is nil, and not
the model.
This error occurs during the answer back from the model editor to the
collection report. It has something to do with the
MAOneToManyComponent's memento having a nil value for #cache.
And in your object the value is actually a collection? Usually the
cache just reads the value from your object.
I am confused. How can I reproduce?
Cheers,
Lukas
