Are you building some sort of modify string?  If so you may need to 're-do' the GetChild on the DDDW in order for it to work.  Many properties on the parent datawindow will cause the child reference to be lost if they are modified.

Hi William;

  Make sure that you do not have more than one copy of the DWO that performs the DDDW functionality in two or more PBLs. If so, the PB runtime might be picking up the wrong DWO instance. Which in turn, might not have all the row values. Also, make sure that your parent DWO's column is in fact declared as a DDDW vs DDLB.  Food for thought.

Regards ... Chris
