Is it possible to handle an application event outside from the managed package.

I have created a managed package which have an Lightning event and a Lightning component, the Lightning component is firing this application event on a click.

How can I handle this event in another component?

I have handled the event but it is not working.

My event

<aura:event type="APPLICATION">
  <aura:attribute name="message" type="String"/>

registering event in my controller

<aura:registerEvent name="appEvent" type="c:aeEvent"/>

these two codes belongs to a managed packages whose namespace is appe.

I am creating an component in another org where i have installed this managed package and in this component I am handling this event.

event handler

<aura:handler name="appEvent"  event="appe:aeEvent" action="{!c.handleApplicationEvent}"/>

but the function handleApplicationEvent is not getting invoked. please help.

This will most likely happen if you've either wrong access rules, namespace access or if the event is not registered properly. I would recommend checking the following

1) Is your component access attribute set to 'global'

2) Try to debug if your event handler was registered successfully using the <aura:registerEvent> call
