Common Pitfalls

I get an error saying "Controller doesn't exist"

Make sure your controller is present in the array of controllers in your App class' static controllers property, and is correctly imported at the top of your App class file.

My renderables are not shown

Make sure that the renderables in your View class are decorated with @layout decorators. Not having any decorators on properties in a View class will have those properties ignored by the rendering engine.

My changes are not reflecting when I open www/index.html

Make sure you run npm run build after every change, or run npm run watch to rebuild on every file change.

My DataBoundScrollView won't scroll if I drag in between the items

The FlexScrollView will not by default create listeners outside of the renderables it draws. You can either create a Famous surface behind the scrollView and .pipe() it to the scrollView, or use a container in the ScrollView.
