I am trying to 'tag' multiple 'points' with multiple tags. I'm tagging my single points successfully. Unfortunately, when i try and use a tag, such as 'test2' on another point as a tag it is either giving me a duplicate entry error if i have my 'unique' set to false or if 'unique' is set to true, it will del my tag for all other points for 'test2' and create a single new one.

Here is what i have for my post data:

Array
(
[Tag] => Array
(
[id] => 4b7af6d7-787c-4f10-aa49-2502c0a80001
[name] => Test2
)

[Point] => Array
    (
        [id] => 4b47c66f-a130-4d12-8ccd-60824051e4b0
    )

)

In my tag model i have this:

public $hasAndBelongsToMany = array(

'Point' => array(
'className' => 'Point',
'joinTable' => 'points_tags',
'foreignKey' => 'tag_id',
'associationForeignKey' => 'point_id',
'unique' => false)
);

I have tried this with 'unique' set as false too. Unfortunately, this will delete any other instances of 'Test2' in the join table ('points_tags').

I have tried this using both save() and saveAll(). Both are giving me this error:

Warning (512): SQL Error: 1062: Duplicate entry '4b7af6d7-787c-4f10-aa49-2502c0a80001-4b47c66f-a130-4d12-8ccd-608' for key 'MAN_ADD' [CORE/cake/libs/model/datasources/dbo_source.php, line 527]

Thoughts????

Suggestions????
