In the meantime, I've been looking at the code.

What you can try: at the top of the delete() function, there are these two lines:

Code:

$this->db->where('id', $this->id);
$this->db->delete($this->table);

Move these two lines down, just before this:

Code:

// Complete auto transaction
$this->_auto_trans_complete('delete');

As far as I can see, this makes sure all relations are deleted first, before the record itself is deleted. From a logic point of view a better solution imho.

Could you try and see if this fixes your problem? If so you can leave the constraints in place.
