Hi there,

I have a simple sidebar extension for different page types.
The SidebarContent field is shown in the admin but won't save any entries.
I checked different examples, the documentation and this forum but I cannot find the problem.

I am very grateful if one of you may help me out here :)

class SideBarExtension extends DataExtension {

   static $db = array(
      'SidebarContent' => 'HTMLText'

   public function updateCMSFields(FieldList $fields) {
$fields->addFieldToTab("Root.Main", new HTMLEditorField('SidebarContent','Sidebar Content'));

Here is one solution I just found out:

Instead of configuring the extension in the config.yml


- 'SidebarExtension'

I have to configure it in _config.php in order to make it work

Object::add_extension('StartPage', 'SideBarExtension');

Does anyone know why? It would be nice to have all the extension configurations in one file.

Did you run "/dev/build/?flush" ?

Also, I think "parent::updateCMSFields($fields);" is not necessary here since "parent" is an abstract class.

I did build it couple of times. That shouldn't be the problem.

Also if I don't put "parent::updateCMSFields($fields);" the new field will not be aligned with the other fields. It will look a bit off then.
