In composite case, the port Ap1 is also defined as composite actor output port via connecting to composite actor output port. And also it is connected to Bp1 port via a relation. I observe that if i disconnect connection to composite actor output port, i can get the list correctly. But if i connect again to composite actor output the list only contains CompositeActor. I think that composite actor conncetion dominate the others and i am getting list without other connected actors.
I hope this will explain the situation much more clearly, --ufuk
