Find(all) query in multiple table

Hi,
Maybe someone can help me with this...
The tables are linked this way:
http://dl.dropbox.com/u/52896949/Screen%20Shot%202012-01-22%20at%201.03.03%20AM.png
What i need is:
Find all Events that a user is linked with.
Witch means: that a user is "owner" (the Events.user_id) or that the
user is staff of (Table Staffs).
So, what i have made is:
----
public function getEventsOf($User_id){

$conditions = array(
'Event.status' => 'active',
'AND' => array(
'OR' => array(
'Event.user_id' => $User_id,
'OR'=>array(
'AND' => array(
'Event.id = Staff.user_id',
'Staff.user_id' => $User_id,
),
),
),
),
);
$users = $this->find('all', array(
'conditions'=> $conditions,
'recursive' => 0) );

return $users;
}

-----
But a error shows up:
-----
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column
'Staff.user_id' in 'where clause'
SQL Query: SELECT `Event`.`id`, `Event`.`user_id`, `Event`.`title`,
`Event`.`description`, `Event`.`country`, `Event`.`state`,
`Event`.`city`, `Event`.`date_start`, `Event`.`date_end`,
`Event`.`pin`, `Event`.`pros_cons`, `Event`.`status`,
`Event`.`created`, `Event`.`modified`, `User`.`id`,
`User`.`first_name`, `User`.`last_name`, `User`.`email`,
`User`.`password`, `User`.`username`, `User`.`country`,
`User`.`state`, `User`.`status`, `User`.`created`, `User`.`modified`
FROM `events` AS `Event` LEFT JOIN `users` AS `User` ON
(`Event`.`user_id` = `User`.`id`) WHERE `Event`.`status` = 'active'
AND ((`Event`.`user_id` = 12) OR (((`Event`.`id` = `Staff`.`user_id`)
AND (`Staff`.`user_id` = 12))))
----

What do i do?
Thanks...
Ivan
