Button on Layout with ClickableLayout

Hi,
I have a HorizontalLayout with LayoutClickListener(). I add a Button on it, without clickListener. When I click on the button, the layoutClick() is not fired. It is only fired if I right click the button, or with a left doubleclick.
Changing the Button in a VerticalLayout and clicking on it, the layoutClick() is fired. Is it possible to get layoutClick fired pressing a button on a layout with LayoutClickListener?
Thank you, Francesco
