ACL Group Permissions, kills parent_id

AclBehavior.php

// this is a snip from a Behavior I wrote that overrides afterSave(...) from the AclBehavior.

// This solves having multiple instances of your model in the ACO/ARO trees. I'm not really sure "what"
// the point of updating an ACO/ARO is in the $created == true case is unless you have defined a single "Group"  
// inheritance as they show in the docs. Clearly that isn't ideal for some setups, but changing the current 
// implementation could break a lot of sites (I actually would want to see a complex case that proves that, I'm only 
// "told" that is the case). At any rate, in my case I'll take care of updating all the other ACO/ARO's that are not 
// at the default parent node for the model. 

// This appears to be a purposeful limitation to basically allow "grouping" but not multiple grouping. In theory
// (and what I think they want you to do is...) you could put groups in groups and users in grouped groups and 
// things would work. That is the kind of line of thought makes ACL really hard to follow IMHO.

// The better solution here would be implement detection of "hasAndBelongsToMany" relationship within ACL. It could
// then iterate over the relationships and update (again, looks pointless to me) all of them with the appropriate
// parent_id.
