Question

I moved my code from my Application to a separate AS class file and now I’m getting the following errors:

1061: Call to a possibly undefined method addEventListener through a reference with static type Class.

1180: Call to a possibly undefined method addEventListener.

.

package managers {


    import flash.events.Event;
    import flash.events.EventDispatcher;

    public class RemoteManager extends EventDispatcher {


        public function RemoteManager() {

        }


        public static function init(clearCache:Boolean = false):void {

            addEventListener(SETTINGS_CHANGE, settingChangeHandler);
            addEventListener(ITEMS_UPDATED, itemsUpdatedHandler);
        }
    }
}

Answer 1

Your code

addEventListener(SETTINGS_CHANGE, settingChangeHandler);

evaluates to

this.addEventListener(SETTINGS_CHANGE, settingChangeHandler);

There is no this in a static method, since it’s designed to function without an instance. Furthermore, you cannot attach an event listener and dispatch events from a static class.

Either change your function declaration to

public function init(clearCache:Boolean = false):void

Or implement a singleton pattern to kinda get a “static class, that dispatches events”.

Singleton with event management.
