Findall In Relational Tables With != Condition

Hi all......

I have two tables jobStatus and notifiactionRules, structures of tables are:

JobStatus:

id : PK
name

notifiactionRules

id : PK
status_id : FK

i want to write a condition in findAll, such that i have to get the names of all job status that are NOT IN notifiactionRules.

I tried this:

$jobstatuslist = CHtml::listData(JobStatus::model()
->findAll(array(
'condition'=>'id!=:status_id',
'params'=>array(':status_id'=>NotificationRules::model()->findAll(),'id', 'job_status_id'))
));

but i am getting error - Undefined offset: 2

can anyone pls help.......
