Infoengine DIRECTION parameter to find hangingChanges in ChangeActivity

Hi,

Looking to create an infoengine task that outputs related information about resulting items in a change activity. A snippet of what I have now is below.. I don't think my DIRECTION value is correct but I'm not sure what value to place in here. Any ideas?

ie:param name="TYPE" data="wt.change2.ChangeRecord2"/>

param Name="DIRECTION" data="theChangeActivity2"/>

param Name="OBJECT_REF" data= (a VR of a ChangeActivity) />

param Name="ATTRIBUTE" data="*" />

This isn't returning anything in the collection. Below is the output.

-<wc:COLLECTION>

 wt.change2.ChangeRecord2 ....

</wc:COLLECTION>
