Hi,

I have a Controller A which has a store S listening to a load event.
When the load event fires I throw a custom event

this.fireEvent('customEvent');

In a Controller B config method I set up a button listening to this event.

Code:
buttonButton: {           	 
            	 'customEvent': function() {
            		 console.log('custom EVENT');
            	 }
             }
The store correctly fires the event but the button doesn't react to it.
