Re: Events - how do I attach additional callbacks to the HelperCollection

Hi,

I've got a case where I want one helper to raise events on other helpers. The concept is that plugins can manipulate the output of a MenuHelper by returning additional menu items at runtime.

Is there a way that I can access an instance of the helper collection and attach additional callbacks that can be listed to? sorry no code samples at the moment, I'm a little bit lost on the way this is implemented, just need a nudge in the right direction.

There's something similar in Croogo:

Trigger events:
https://github.com/croogo/croogo/blob/1.5/View/Helper/LayoutHelper.php#L313

Setup another helper to listen for that event:
https://github.com/croogo/croogo/blob/1.5/Plugin/Menus/View/Helper/MenusHelper.php#L32
