The selection from the INNER entity is passed to the child task via the $selection string, which can be customised using the _cm_getPkeyNames() method. The $where string is also extracted from the same object and passed in the $where string, which can be customised using the _cm_getWhere() method. If no selection is made then $selection will be set to $where.
You therefore need to put some code in the _cm_getWhere() method if you are not making any selections from the INNER entity.
I have tried navigating from a LIST2 to a ADD4 and I see the $where string correctly passed to the ADD4 task where it is passed to the initialise() and _cm_initialise() methods. It is still there when it is passed to the getInitialDataMultiple() method, but is converted into an associative array before being passed to the _cm_getInitialDataMultiple() method. There is nothing in the standard code which loses the contents of $where. Where does it happen in your code?
