One vertical ToggleButtonBar (T1) controls a Viewstack (V1).
Each Canvas of the viewstack is divided into 2 zones: top one with
a horizontal ToggleButtonBar (T2) and the bottom which is another
viewstack (V2) controlled by T2. This way there is a T2 and V2 for
each Option of T1.
I use "Sequence" effects as hide & show for V1. This
sequences affect directly to the components inside the according
canvas (V2 and T2). This way, when I press a button of T1, it shows
the appropiate canvas in V1, so I use a Move effect to make T2
appear and a Fade to show V2. The problem is that It should wait
the effects on each canvas of the viewstack, but all they do is
overlaping each other.
I really don't know what is wrong or if this is the correct
path to do it... Thank you!
