My guess would be that this is remnant of the old navigation system (Cook)
You should use the new one (Chef) which is more robust and generic:
aFAMIXType queryIncomingAccesses
you can then refine the query:
aFAMIXType queryIncomingAccesses atClassScope
-> all the classes that access an attribute of aFAMIXType
aFAMIXType queryIncomingAccesses atClassScope withoutSelfLoops
-> same, but aFAMIXType will be filtered out (if it does access its own
attributes which it should)
aFAMIXType queryIncomingAccesses opposite
-> all behaviourals (presumably methods) that access an attribute of
aFAMIXType
