Import Controller + Session = Fatal error
Hello,
I have the following issue :
I have 2 controllers : Controller A and Controller B .
I need to use some logic( call a method ) in Controller A that is defined in Controller B.
Inside Controller A I use :
App::Import('Controller','B');
$controllerB = new BController();
$controllerB->someMethod();
In controller B I have :
public function someMethod()
{
return $this->Session->read('somevar');
}
The problem is that when someMethod is called in controller A I receive a fatal error:
Notice (8): Undefined property: BController::$Session
and
Fatal error: Call to a member function someMethod() on a non-object
I have specified var $components = array('Session') and I tried a lot of other solutions but it just wont work if I use the session object inside a class that has been imported.
Can you guys please give me a hand ?
I appreciate,
Dragos

you should never ever use a controller inside another controller!
if you are in need to do that it is a clear signal that you are doing something awefully wrong here.
put that code you need in both controllers inside a model method, a component, or even a lib and then just call it from each of those two controller actions.

Thank you for the reply .
I know is bad practice , but there are cases where it would be very useful .
You are asked to develop a future , you create the controller for it and it's fine ...than the client comes and says he wants the same logic you developed earlier to appear on a new page.
Because you did not know that from the beginning you are a trapped ... you cannot call that controller logic in the new page because it will fail...and to move the logic inside a lib , will be time consuming and the original controller will have to be re-tested and so on.
