   I floundered around with this as well, following the tutorial at http://grahambird.co.uk/cake/tutorials/ajax.php

   I solved it by copying the vanilla app_controller.php file from /cake/ to /app/ and adding the helpers info (#1) there. I’m new to Cake but I presume that as the $javacript reference is in the default view, that variable has to be set up in the generic controller.

   Thanks for the tip- this saved me a few hours…

   Also this and similar things can happen if your database is out of synchron. For example, i’m developing at my local server, and doing svn commits to another server. The commit invokes a script that immediatly updates the server version from the repository, and sometimes I can get similar messages if I don’t care enough to sync the databases.

   This was a big help! The tutorial I was following also left out the $helpers var, so this was very useful.

    Yeah, I’ve run into the undefined variable: javascript a bunch of times… Finally figured out that if you are defining your helper array in app_controller.php & you happen to be missing a model or have an improperly named db table, the error gets reported in the title of the page, but the view displays the undefined var: javascript. In a nutshell… make sure that your app_controller is entirely valid if yr defining helpers there.

    I was experiencing this same problem, but it was firing at my default layout. To remedy this, I had to put it in my app_controller.php file so it was available at a higher level.

    
class AppController extends Controller {
var $helpers = array('Html', 'Javascript');
}


    Remedied all my issues. Thanks for pointing me in the right direction.

    I thought I should add to this:

    Went through the same problem and this post helped me figure out the cause (trying to render a non-existent view).

    The thing is I was messing with custom flash message layouts, and the non-existent view was a custom flash layout that was specified earlier, but then changed. No matter how many times I reloaded the page, it kept the same way. I deleted all the cache files, even restarted Apache hoping that something was being cached in the memory level. Nothing worked.

    Only after some 20 minutes I realized the name of the custom layout was written to the session itself, so regardless of me having changed it in my code, it was still being called.

    The solution was to create the non-existent file temporarily and reload. It worked. I then removed this file and tried again: everything worked perfectly.

    Just keeping this here in case it’s helpful to anyone.

    Cheers
