Sorry for the many posts. Looks like the post_delete operation on CONTROL2 is attempting to the parent controller CONTROL1. The URL is correct (verified using extra-data on debugger and via network sniffer wireshark). It uses the correct controller for get_one and get_all, but the wrong (parent) controller for post_delete (have not confirmed edit operation yet). Thanks.
