Scrollview + surface dynamic content

I have been playing around with famo.us and am currently stuck at getting dynamic content to scroll inside a scrollview/surface

I currently have a scrollview with one surface and on render of the content i check the size of the content and set the same height to the surface. I do the same on resize.

I was wondering if there is a better solution with famo.us to handle surfaces with dynamic content within a scrollview.

Code is basically boilerplate so no examples here. It's more of a "is it possible" question.

Currently there is no easier way to do it. When you say dynamic content I assume you are talking about a true-sized object. I see you mentioned checking the height on render, which again has been a solution before Famo.us makes this more accessible.

I have achieved dynamic content inside a sequentialLayout by creating a Custom View object that takes the same parameters as Surface. The view then creates a frontView that is visible and a backView that is not. If a size parameter comes in at [500,true] for example, backView will take the true-sizing and frontView will calculate the actual size in pixels. Then on resize, we can use backView as a sort of ruler, to do the dynamic sizing, while updates to the actual height in pixels are applied to frontView.

This sort of thing does seem harder than it should be, but that's because this behavior is a strength of the traditional box model. By throwing out the box model, we benefit in many other areas, but this is not one of them!
