Kenneth Moreland 42bc9a393c Fix gaps in type support
With recent changes to allow a configuration to change the default
types, storage, and cell sets, it is possible to feed filters and other
components types they were not previously expecting. Fix feature gaps
where these components were not accepting the types they should.
