Famo.us RenderController not working under SequentialLayout? - layout

Question

I have added a common Surface and a Scrollview (actually a FlexScrollView) to a SequentialLayout and then added the layout to my View as the following code shows:
function _createCameraView() {
var layoutViews = [];
this.cameraView = new View({
size: [undefined, this.options.footerSize]
});
var layout = new SequentialLayout({
size: [undefined, this.options.footerSize],
direction: Utility.Direction.Y
});
var backgroundSurface = new Surface({
size: [undefined, 120],
content: 'some content',
classes : ['photo-guide-content'],
properties: {
backgroundColor: 'transparent',
zIndex: 4
}
});
// detail list
var detailsList = new FlexScrollView({
layout: ListLayout,
direction: Utility.Direction.X, // set direction to horizontal
paginated: true,
//autoPipeEvents: true,
useContainer: true,
container : {
size: [undefined, 60],
properties : {
'z-index' : 5,
}
}
});
layoutViews.push(backgroundSurface);
layoutViews.push(detailsList);
layout.sequenceFrom(layoutViews);
this.cameraView.add(alignModifier).add(layout);
}
Then I've added a RenderController on another view and I'm using it to display my cameraView like this:
function _selectCamera() {
if (!this.cameraView) {
_createCameraView.call(this);
}
this.footerRender.hide(this.mapView);
this.footerRender.show(this.cameraView);
}
I know I don't need to call the hide method from the render on the function above, just the show method and it should swap the views with a smooth opacity transition, which is defined by default. Although when using this Sequential Layout I'm not getting this effect. I know it has to do with this layout because I've tried to switch the layout to a FlexibleLayout and a GridLayout, and it works fine with these two. So, my question is, why doesn't work with the SequentialLayout? I've also noticed it has a method called setOutputFunction(outputFunction), is there a way to use it so the layout uses the opacity returned from the RenderController or how can it be fixed some other way?

Try adding a getSize method to your view.
Something like this:
this.cameraView.getSize = function() {
return [undefined, undefined];
};
