    Difficulty with widget and login via admin Link to this post


    I have SilverStripe 2.4.2 running, with the blog module version 0.4.1. I want to show, let's say, the TagCloudWidget on all pages instead of only the blog section. So as per http://doc.silverstripe.org/widgets I disable the whole widget thingie from BlogTree.php etc. and put the following in Page.php (controller):

    function MyTagCloudWidget() {
       $widget = new TagCloudWidget();
       return $widget->renderWith('WidgetHolder');

    I use $MyTagCloudWidget on Page.ss to show the widget. This works, but when I want to logout of the CMS I get an error:

    [User Error] Uncaught Exception: Object->__call(): the method 'data' does not exist on 'Security'
    GET /Security/login?BackURL=%2Fadmin

    Line 724 in /Applications/MAMP/htdocs/sapphire/core/Object.php

    716             default :
    717                throw new Exception (
    718                   "Object->__call(): extra method $method is invalid on $this->class:" . var_export($config, true)
    719                );
    720          }
    721       } else {
    722          // Please do not change the exception code number below.
    724          throw new Exception("Object->__call(): the method '$method' does not exist on '$this->class'", 2175);
    725       }
    726    }

    This on a local MAMP install, but the same happens on a 'real' server. If I remove the $MyTagCloudWidget call, I can login again. Any ideas?


    Edit: I seem to be able to solve it by using a separate Security_login.ss template, but still I would like to know why the above will happen without such thing. It happens with a vanilla install too, using the BlackCandy theme...

    Hi there - I'm having exactly the same issue - did you ever resolve this other than a separate Security_login.ss file?

    Many thanks,

    I've worked around this by changing line 54 in TagCloudWidget.php. I have just one BlogHolder on my website, so for me this did the trick.

          //$container = BlogTree::current();
          $container = DataObject::get_one('BlogHolder');
