I just clued in to the fact that the data array was in the wrong form.
I'm using contain to grab the User's name info and the array looked
like:

Array
(
[0] => Array
(
[Foo] => Array
(
[id] => 1
[bar] => 1
[another_field] => 0
[user_id] => 3
)

[User] => Array
(
[first_name] => ...
[last_name] => ...
[organisation_name] => ...
[id] => 3
[label] => ...
)

)
...

Of course, I need:

Array
(
[Foo] => Array
(
[0] => Array
(
[first_name] => ...
[last_name] => ...
[organisation_name] => ...
[id] => 1
[label] => ...
[bar] => 1
[another_field] => 0
[user_id] => 3
)
...

I solved it by using the most excellent Set class.

$tmp = $this->paginate();

$this->data['Foo'] = Set::merge(
Set::extract($tmp, '{n}.User'),
Set::extract($tmp, '{n}.Foo')
);
unset($tmp);

I had to put the User extraction first in the merge params so that
Foo->id wouldn't get clobbered because contain grabs User->id even if
it's not in the fields list.
