I upgraded an app to 2.01 and can’t figure out why I am getting a

undefined method `param\_posted?’ for #\<ControlPanelController:  
0xb748ba18\>

The controller should be inheriting this.

class ControlPanelController \< ApplicationController

there is no method called param\_posted? unless you defined it in your  
applicationController.

How are we supposed to know this if you don’t post the relevant code?

Yes that was my stupidity, I forgot that I added this in application  
controller.

Thanks for reminding me.
