CakePHP: Passing $this->params['form'] in a requestAction call?

Question

How can I pass $this->params['form'] to the controller action I specify in requestAction so that I can use the variable in the same way by calling $this->params['form']?

Here is what I'm trying (but isn't working):

$this->requestAction('/reports/grid', array('params["form"]' => $this->params['form']));
$this->requestAction('/reports/grid', array('$this->params["form"]' => $this->params['form']));

Answer 1

$this->requestAction('/reports/grid', array('form' => $this->params['form']));

Answer 2

According to the 1.3 documentation, you'll need to specify each parameter you want to send off in the request in the pass or named parameter key - http://book.cakephp.org/1.3/en/view/991/requestAction

echo $this->requestAction(array('controller' => 'articles', 'action' => 'featured'), array('named' => array('limit' => 3)));

echo $this->requestAction(array('controller' => 'articles', 'action' => 'view'), array('pass' => array(5)));

So, it should be something like

$this->requestAction('/reports/grid', array('pass' => array($this->params['form'])));

Note - There are very few good reasons you would want to use requestAction. Please read up on the performance penalties if you haven't already.
