PayPal IPN Response and Table Updates

[eluser]johnnyletrois[/eluser]
The problem is

Code:

$result  = $this->Common_model->getTableData('reservation', array('id' => $list_id))->row();

is returning

Code:

array(0) { }

If i manually put an assign a value to $result then everything works fine (DB is updated, email is sent). But getTableData is not returning anything in this instance although it works elsewhere.
