Actually, up until today, bizobjs worked differently than any other
object when used as a DataSource. They would only allow DataField values that
corresponded to column names, or, for derived values, method names that
returned read-only values. I've just posted a change that allows data binding
to bizobjs the same as any other object, as well as the special handling for
data column values. Now you can add an attribute to the bizobj for the password
confirmation value, and then bind the control to that. No need for the
multiple-step process I outlined earlier.

When the value of the text control changes, it will be flushed to its
DataSource when the control loses focus, or when the internal form method
activeControlValid() is fired. You shouldn't have to do anything else.
