Question

My rendered method is being called before _initializeLayout:

var _initializeLayout = function() {

    console.log('initializeLayout...');

    Controller.layout = new Layout();

        Controller.layout.on("show", function() {

        vent.trigger("layout:rendered");

    });

    vent.trigger('app:show', Controller.layout);

};

I use the layout in the on rendered method:

// controller attach a sub view/ search View
vent.on("layout:rendered", function() {
    console.log('layout:rendered =>StartController');

    // render views for the existing HTML in the template, and attach it to the layout (i.e. don't double render)
    var inspectorStartView = new InspectorStartView();
    Controller.layout.inspector.attachView(inspectorStartView);

    var playerStartView = new PlayerStartView();
    Controller.layout.player.attachView(playerStartView);
});

When I try it, my on rendered callback is called before _initializeLayout(). I have it calling _initializeLayout in the router/controller method:

Controller.go_inspector_control_center = function(term) {
        _initializeLayout();
        //vent.trigger("search:term", term);
    };

I just ran it again and found that an event was being triggered from a different controller’s _initializeLayout() method:

   // private
var _initializeLayout = function() {
    console.log('initialize Start Layout...');
    Controller.layout = new Layout();
    Controller.layout.on("show", function() {
        **vent.trigger("layout:rendered"); // <--**
    });
    vent.trigger('app:show', Controller.layout);
};

It appears that the events need to have unique names. I’ll try that. If anyone knows please chime in.

You just can’t take us Java guys anywhere. The answer (in Javascript) is that I do need to name my events uniquely. Makes sense when you think about it.

Although most event systems I’ve worked with X11/Java you don’t name your event you use what they give you.

Here is a stackoverflow question on event naming.

I hope my public learning is helping others. 😉
