Passing and retrieving and object type variable from SSIS Package Parts

I am able to pass regular types in and out of SSIS Package Parts. I am using a single (and only) Script task inside a package part which as an input takes an object (which holds a recordset) and also returns an object variable (as a recordset).

I am not able to pass and retrieve an object type variable from SSIS package parts.

Any ideas?
