Overrides and Defaults don't appear to be working.

[allen]

e.g.

'overrides' => array (
'account' => '{$event-save-user-account-id}',
),
'defaults' => array (
'account' => '{$event-save-user-account-id}',
),

When debugging the form submission for the above example the {$event-save-user-account-id} param has be set but the account field is still not set by the chained event.
