ok I figured out my problem. (I think) when a update is applied it happens in the following order.. please correct me if i'm wrong.
..apply the edits on the object in question _save function called apply the edits to the one-to-many & many-to-many fields referenced. my issue is that the many to many has a custom update method which I am calling in _post_save and not in the actual field's manipulator.. Is this correct? is it as simple as just moving the code into tags manipulator??? regards Ian.
