Peter knows this example better, so I'll ask him to answer.  Keep in mind
that with pay-as-you-go, every level of functionality adds code.  The
smallest DG would not expect any changes:  it would just display the data
in its columns.  The next level of change support is adding and removing
whole rows.  After that comes replacing a row, then we get into changing
fields in the rows.  Each level adds more code and complexity in handling
things like selectedItem/selectedIndex.  I envision several kinds of view,
controller and model beads to manage this complexity.  I'm not sure which
ones have been built yet.
