Hello,

I'm attaching the test case for this issue. The test case includes some ifs to prevent too many objects to be created and/or to help testing.

Unmodified, this will output:

[] 0 [] 0 [] 0

just changing the CustomMapperExtension if to False (effectively deleting the create_instance override) restores full software functionality. I couldn't understand what's the problem - just to let you know, my software worked 100% until i reached this many-to-many relations part - manytoone and onetomany work fine.
