no haven't tested, 'cause the application is very close to the release, and will be released on 4.0.7. v4.1 is not stable yet.
But I have found a solution, don't know if is a best one but works: my layout is card, and one of the cards is the grid panel, and fit's the card, then I configured it's viewConfig with autoscroll: true, didn't worked, this was the first try and thought should work. Then came the thoughts with the layout, if it fits the card, and the card is in center of the border layout, why I should set the height !!!!!?. But tried, and added maxHeight to the viewConfig and worked. So the solution is:
it's a right one ?
