How to indicate data output from a subactivity in an Activity Diagram?

as said in the title I am trying to indicate the output of data from a subactivity in an Activity Diagram. I am torn between Object-Nodes and input pins.

What is correct in this case?

Input and output of Activities are routed through ObjectNodes. For the input you use an ActivityParameter which is a specialized ObjectNode. ObjectNodes are drawn as little squares at the border of Activity. ActivityParameters are shown as flat rectangular shapes also at the border of Activities.
