Re: paginator with user defined page sizes...

Hey,

seems a bit too complicated to me...

I suggest you just wrap the dropdown in a form, use a submit on the
same page ($this->Form->create('Modelname', array('url' => $this-
>here));) to send the form to the same action you're in at this
moment.

In your controller use a RequestHandler-Part to get changes of the
dropdown and write them into a session variable. Then use a paginator
defintion directly within the controller, and set the limit of the
paginator to the value of the depending session-key.

That should be a 2-minute task, if you have any questions just ask, I
will post the code for you if you cannot get any further.

Hint:
To define the paginator from within an action (and not globally for a
whole controller), use the following code in your action:

public function index() {
$this->paginate['Modelname'] = array(
'conditions' => array(
'Modelname.deleted' => false),
'limit' => 10,
'order' => array(
'Modelname.created' => 'DESC'
)
);
$results = $this->paginate('Modelname');
$this->set(compact('results'));
}

(the code above implies you would use a condition on not-deleted
entries and an ordering of the field created in a descending way)

Second hint: replace the hard-coded limit of 10 to a Session key (e.g.
$this->Session->read('Settings.Model.action.limit'); )
