I ported to javaFX the Android LinearLayout panel(it extends Pane)
It work fine in most use except in a ListCell updateItem method.
I create this LinearLayout and I call the setGraphic method of ListCell.
The layoutChildren method is never called on this LinearLayout object so the display is completely wrong.
In order to find a solution to my problem, I try to force the layoutChildren call to the ListCell object: it works.
In this method I try to force the call to the layoutChildren method of my object LinearLayout: it seems to work because the traces shows me the correct positions of the objects included in it.
unfortunately this has no effect on the final display on the screen: the display is completely wrong again
