Oops, missed out the view (note the HATBM field indexes):
<?php echo $form->create("Post", array("action"=>$this->action)) ?>
<?php echo $form->input("Post.id") ?>
<?php echo $form->input("Post.name") ?>
<?php echo $form->input("Tag.0.PostsTag.tag_id", array("options"=>
$tags))?>
<?php echo $form->input("Tag.0.PostsTag.weight")?>
<?php echo $form->input("Tag.1.PostsTag.tag_id", array("options"=>
$tags))?>
<?php echo $form->input("Tag.1.PostsTag.weight")?>
<?php echo $form->end("Submit") ?>
