Description
When I'm using Marionette, I'll occasionally make errors such as accessing a region that doesn't exist e.g.
var MyView = Marionette.LayoutView.extend({
regions: {
main: '.main-hook'
},
onRender: function() {
this.showChildView('layout', someView());
}
});
var view = new MyView();
view.getChildView('layout');
The exception I get comes from inside Marionette as a Cannot read property currentView of undefined or this.getRegion(..) is undefined. While I can chase the stacktrace back to find out the exact issue, it would be much better if I could get the following error:
LayoutError: 'layout' is not a region on MyView. The available regions are: 'main'
This is just to illustrate my point - if we have the information on why something isn't going to work we should tell the developer to save them time.
