I think you're on the right track on the object identifciation perhaps being off. However, without information as to how your NameMapping is identifying the object and information about how the object shows up in your application, there's little I can do.
If you could provide:
1) Screenshot showing your NameMapping where the object being identified is indicated. Please make it of the "Mapped Objects" panel of NameMapping so we can see the full identification tree
2) Screenshot showing the Object Browser where the component in question is highlighted with available properties (Advanced view would be preferrable).
3) Screenshot or code of the test steps your are attempting to execute.
