Changing model data in beforeSave of Behavior when using saveAll

Question

I'm trying to write Meta behavior for a project I'm working on, which will allow me to assign custom variables / attributes to the model, similar to how you can create custom fields in a wordpress message.

I created a Meta behavior that associates a metamodel with the model on which it acts, and also has a beforeSave callback that passes through the model data variable and puts the model name in a meta array.

Everything is saved, but when I check the database, the model field is returned empty.

Database structure for Meta p>

id - A unique if for the meta
model - The name of the model that this meta entry is associated with
foreign_id - The id of the above model that this meta entry is associated with
key - Name of the meta variable
value - Value of the meta variable

The data coming into the saveAll function from the form,

Array
(
    [Page] => Array
        (
            [id] => 12
            [name] => Test
            [slug] => a/b/c/d
            [layout] => 0
            [body] => Test multilevel
        )

    [Meta] => Array
        (
            [0] => Array
                (
                    [id] => 1
                    [key] => page_title
                    [value] => About Us
                )

            [1] => Array
                (
                    [id] => 6
                    [key] => test4
                    [value] => test
                )

            [2] => Array
                (
                    [key] => test3
                    [value] => lala
                )

        )

)

and after he performed beforeSave behavior, he

Array
(
    [Page] => Array
        (
            [id] => 12
            [name] => Test
            [slug] => a/b/c/d
            [layout] => 0
            [body] => Test multilevel
            [modified] => 2010-05-04 15:56:54
        )

    [Meta] => Array
        (
            [0] => Array
                (
                    [id] => 1
                    [key] => page_title
                    [value] => About Us
                    [model] => Page
                )

            [1] => Array
                (
                    [id] => 6
                    [key] => test4
                    [value] => test
                    [model] => Page
                )

            [2] => Array
                (
                    [key] => test3
                    [value] => lala
                    [model] => Page
                )

        )
