before_relationship_add after returning after relationship informaiton

Question

Hi everyone. 
 I'm having an issue currently with before_relationship_add, what I am wanting to do is to interrogate the change to a 1:1 relationship. So for instance my idea was: 
 Relationship changes from A to B. 
 I load A and find the old name. 
 I load B and find the new name. 
 I add a note to say "Changed A to B". 
 However in the before_relationship_add and the after_relationship_add both seem to return B no matter what I do. I am using the "$arguments['id'] as my reference to check this. 
 Any ideas on this? 
 Thanks,

Per Sugar's documentation "One-to-One: This type of relationship is the most restrictive and results in a relate field in both modules . You can create the relationship in either the primary or related module." 
 What this means is that if you are working in a record and change the related record from A to B, as soon as A is saved, the related record becomes B, because relate fields are simply Foreign Keys to the related record. 
 So to see that A is about to change to B you should use a before_save logic hook. There you can see the before and after values using the bean: 
 $ bean -> fetched _row['your_relate_field'] // the value before the change 
 and 
 $ bean -> your_relate_field // the value it will be once saved 
 
 Hope this helps,
