It takes longer than expected, the event handling of views in B4I and B4J is strange.
For the background:
I have a transparent panel on the root panel on this panel are the cards, so that you can see the card even if you are out of the range of the custom view.
The transparent panel has no events, but it still covers the events of the 2 buttons below (previous and next).
On B4A it works perfect, but on B4J and B4I not.
