    Hello Wayne,

    As you know, a context is automatically destroyed when its contextView is removed from stage.


    private function onRemovedFromStage(event:Event):void
        _logger.debug("Context view has left the stage. Destroying context...");
        _contextView.removeEventListener(Event.REMOVED_FROM_STAGE, onRemovedFromStage);

    You can use event.stopImmediatePropagation(); in the handler of Event.REMOVED_FROM_STAGE in your contextView (your module) to prevent the framework from listening for that event. The context won't be destroyed, but, I think that you'll run into problems if/when you want to add the module to the stage again.

    I'm not sure if there is a more elegant solution to this, that's why I've notified Shaun and creynders, in the hope they can give you additional solutions on how to detain a childContext.

    Can you tell us why do you need to keep the module's context alive when you remove the module?

    Thank you very much! Great!
    that's good way,I'm going to test it.
    Reason for keep the module's context alive is :
    i want to use the module as a singleton.
    I don't want to rebuild the module instance, when the module is added to displayl list again.Repeat an instance is created, a waste of system resources, but also the risk of leaking

    You're welcome, Wayne. Since you're content with this solution, I'll mark this discussion as resolved. You can re-open it, if need be.
