there are two ways to update a BE form after changing a field value.
Both do a full reload of the form which includes saving the current
values to DB. So in your "other selectbox" you can react on the new
value of the "triggering selectbox".

1. $TCA[$tablename]['ctrl']['type'] = $field
This configuration option is intended to switch between different types
of records, e.g. content element types. This does not only reload the
BE form but offers the opportunity to change the appearance of the form
(see TCA feature "palettes")

2. $TCA[$tablename]['ctrl']['requestUpdate'] = $fieldlist
This configuration option might be more appropriate in your case. Here
you can define a list of field names that simply trigger a reload of the
BE form (including saving the current values like above).

Have a look at the online documentation for more details:

Cheers,
Thorsten
