= Problem Description =
== Expected ==
When a new `RefillSeries` is created, `SERIES_CODE_COUNT BalanceCode`s should
be created as well.

== Actual ==
No `BalanceCode`s are created. When `readonly_fields` is unset,
`SERIES_CODE_COUNT` objects are created, as expected.

Creating new `BalanceCode`s directly (not inlined in the `RefillSeries` admin
interface) works as expected when `readonly_fields` is set.
