My guess would be that you have everything set up correctly for render. But that on postback your bobject list contains uninitialised objects. Primitive values on it will be reassigned from the posted data so maybe you didn't notice.
Is your manageAdminAobject in request scope? I have not heard of any EL bug that correctly resolves expressions during render phase, but fails during postback phase.
