Sorry for not replying sooner- I am not getting notifications by email like I am supposed to when subscribed to a thread....anyway...
Kelly- I did play around with making 2 layers (feature/dynamic) and one visible/not. That worked ok, as long as remember to modify the other widgets that control which layers are visible in the TOC or legend widget since i dont want to really have 2 layers of the same data listed. This issue was one of the (many) things Esri logged for me as a bug:[#NIM092265 If a map service with a relationship is added to a Flex Viewer 3.3 application as an operational layer, the related records will not show up in the attribute table. ]
This is one of the easier things I am trying to do with the 3.3 viewer & related data....like being able to view a date/time field in its entirety, being able to configure the related records (alias, format, etc), you know, things that seem like they should naturally be possible.
